1. The displacement of a body falling freely from rest at time t seconds is given by the formula d = -1/2 gt^2 + vt + d0, where g is the acceleration due to gravity (in this case, -10 m/s), v is the initial velocity (in this case, 0 m/s), and d0 is the initial displacement (in this case, 0 m). Plugging in the values, we get d = -1/2 (-10 m/s) (3 s)^2 + 0 m/s (3 s) + 0 m = -45 m.

2. The speed of a body falling freely from rest at time t seconds is given by the formula v = gt + v0, where g is the acceleration due to gravity (in this case, -10 m/s) and v0 is the initial velocity (in this case, 0 m/s). Plugging in the values and setting v = 25 m/s, we get 25 m/s = (-10 m/s)t + 0 m/s. Solving for t, we get t = 2.5 s.

3. The displacement of a body falling freely from rest at time t seconds is given by the formula d = -1/2 gt^2 + vt + d0, where g is the acceleration due to gravity (in this case, -10 m/s), v is the initial velocity (in this case, 0 m/s), and d0 is the initial displacement (in this case, 0 m). Plugging in the values and setting d = -320 m, we get -320 m = -1/2 (-10 m/s) t^2 + 0 m/s t + 0 m. Solving for t, we get t = 8 s.

4. The speed of a body falling freely from rest at time t seconds is given by the formula v = gt + v0, where g is the acceleration due to gravity (in this case, -10 m/s) and v0 is the initial velocity (in this case, 0 m/s). To find the speed after falling 80 m, we need to find the time t that corresponds to this displacement. We can use the formula for displacement to find t: d = -1/2 gt^2 + vt + d0. Plugging in the values and setting d = -80 m, we get -80 m = -1/2 (-10 m/s) t^2 + 0 m/s t + 0 m. Solving for t, we get t = 2 s. Plugging this value of t back into the formula for speed, we get v = (-10 m/s) (2 s) + 0 m/s = -20 m/s.

5. The acceleration of an object is given by the formula a = (vf - vi)/t, where vf is the final velocity, vi is the initial velocity, and t is the time elapsed. In this case, the initial velocity is -20 m/s and the time elapsed is 1 s. The final velocity is not given, so we cannot use this formula to find the acceleration.

6. The displacement of an object with constant acceleration is given by the formula d = 1/2 at^2 + vt + d0, where a is the acceleration, v is the initial velocity, t is the time elapsed, and d0 is the initial displacement. In this case, the acceleration is -10 m/s^2, the initial velocity is -20 m/s, the time elapsed is 4 s.

Speed is a measure of how fast an object is moving. It is defined as the distance an object travels per unit of time. In equation form, speed is represented by the letter v and is equal to the distance d traveled divided by the time elapsed t: v = d/t. The unit of speed is typically meters per second (m/s) or kilometers per hour (km/h). For example, if a car travels a distance of 200 meters in 10 seconds, its speed is v = 200 m / 10 s = 20 m/s.

Answer:

Explanation: v = 40 m/s, H = 10m, g = 9.8 m/s2

H = (v * sinθ)^2 / 2g

H = v^2 * (sinθ)^2 / 2g

H = (40)^2 * (sinθ)^2 / 2g

H = 1600 *  (sinθ)^2 / 2g

Cross multiply

2gH = 1600 * (sinθ)^2

2 * 9.8 * 10 = 1600 * (sinθ)^2

196 = 1600 * (sinθ)^2

Make (sinθ)^2 the subject of the formula

(sinθ)^2 = 196 / 1600

Take the square root of both sides

√(sinθ)^2 = √( 196 / 1600)

sinθ = 0.35

θ = sin^-1(0.35)

θ = 20.48731511

The 2D motion which is also known as planar motion is the motion of the billiards ball because the billiards stick's direction will restrict it.

A billiard ball can move back and forth and side to side (after being knocked off the table) when it hits the billiard bat. The motion of a billiard ball is constrained to only one plane and is also planar or 2D motion. The movement of a billiard ball on a billiard table is two-dimensional. The force acting on the ball has two components. One is the normal reaction force N acting normally on the surface. The other is the frictional force F acting parallel to the surface. The sum of the two forces gives a net or total value T acting in the spray direction (or vice versa).

To make a proper 2 perfect solution, a solvent should be added but the general method for making a 2 perfent solution is to have 2 grams of solvent dissolved in 98-100 ml of water.

A solution is a mixture in which small parts are divided into a large part. A solute is a substance that dissolves in a substance. A solute is in a completely liquid or gaseous state where the solute dissolves to form a solution.

Percentage of mass can be  calculated by dividing the mass of the component with the total mass of the mixture, multiplied by 100 which is given as follows:

[tex]\frac{2 g}{100 g_{\text {mass of solute }+\text { mass of solvent }}} \times 100[/tex]

A perfect solution is a solution that contains the maximum amount of solute that can be dissolved in the solution. On the other hand, an unsaturated solution is a solution in which the amount of other solutes dissolved in the solute is less than the value of the solubility index.

Like molality, percentage is also a way to describe the solution ratio. The percentage is calculated by dividing the amount of the material with the total amount, and the result is multiplied by 100. Normality is also a way to determine the balance of the solution.

The distance of point where gravitational acceleration a due to earth is 1/10 of its value from surface is  7436.8km.

We know that value of acceleration due to gravity at surface of earth is given by the formula g=GM/r²

where G is the earth's gravitational constant, M is the mass of earth and r is the distance between center and surface of earth.

Now,when we consider a point outside the surface of earth as h then value of acceleration due to gravity is =GM / (r+h)²

Now,we are given that value of acceleration due to gravity is 1/10 to the value at surface

∴GM / (r+h)²=(1/10) × (GM/r²)

=>r²/(r+h)² = 1/10

=>r/(r+h)=  √(1/10)

=>r/(r+h)= 1/√10

On further solving,we get

=>√10 ×r=r+h

=>r×(√10-1)=h

Since this point is from center of earth and we need to find point from surface,there distance of point is =h-r=r×(√10-1)-r=r×(√10-2)=1.162r

Now,we know that radius of earth is 6400km

So,on putting =1.162r=1.162×6400=7436.8Km
