A freight train initially moving at +10m/s decelerates at a rate of -0.1m/s^2. How far does it move in 30 seconds?
Answer:
255 [m].
Explanation:
1) the formula is (d - requred distance, V₀ - initial velocity, t - elapsed time, a - deceleration):
[tex]d=V_0t+\frac{at^2}{2};[/tex]
2) according to the formula above the required distance is:
d=10*30-0.5*0.1*900=300-45=255 [m].
Apply second equation of kinematics
[tex]\\ \tt\longmapsto s=ut+\dfrac{1}{2}at^2[/tex]
[tex]\\ \tt\longmapsto s=10(30)+\dfrac{1}{2}(-0.1)(30)^2[/tex]
[tex]\\ \tt\longmapsto s=300+(-0.1)(450)[/tex]
[tex]\\ \tt\longmapsto s=300-45[/tex]
[tex]\\ \tt\longmapsto s=255m[/tex]
Suppose wind blows on the model house from the left and
also produces an upward force on the roof. What reaction forces are
needed to support the weight of the roof and counteract forces from the wind?
The reaction force is the force that counterbalances the weight of the roof and acts upwards.
What is reaction force?The question is incomplete but I will try to help you the much I can. The image of the house is not shown hence the free body diagram can not be produced.
However, let me explain to you that force is a vector hence it has direction. The total resultant force is obtained by taking the direction of all the forces into account and this is called resolution of the forces. The reaction force is the force that counterbalances the weight of the roof and acts upwards.

Three materials were rubbed with an insulating cloth and tested to determine their charge. The table shows the results. Which material could be a metal?
Answer:
When two materials are rubbed together, the material with the greatest affinity for electrons is the material which takes electrons away from the other material. Saran wrap takes electrons from nylon and acquires the negative charge. In turn, the nylon loses electrons and becomes charged positively.

A bus travels a total of 350km in 150 minutes. What was its average speed in km/h?#
Answer:
140km/hr
Explanation:
This is a simple converstion.
We know that the bus travels 350km/150min.
We want to know the speed in km/h. All we need to know is that per 1 hr there are 60 min.
350km/150min * 60min/1hr (we want to make sure that the value we are trying to eliminate, in this case the minute, is on the opposing side.)
(350*60)/150 = 21,000km/150hr
let's simplify to only per 1 hr.
21000/150 = 140
150/150 = 1
Therefore, the speed of the bus is 140km/hr
A bus travels a total of 350 km in 150 minutes, so the average speed of the bus in km/hr will be 140 km/hr.
What are Average Speed and Average Velocity?The object's average speed is how far it travels overall in a predetermined amount of time. The scalar quantity represents the average speed. It has no direction; instead, magnitude is used to describe it.
Average Speed = [tex]Total \ Distance/Total\ time[/tex]
An indicator of a vector is average velocity. Average velocity is calculated by dividing the change in position or displacement by the intervals during which it occurs. The average velocity may be positive or negative depending on how the displacement is dispersed. The standard international unit of average velocity is meters per second (m/s).
Average Velocity = [tex]Total \ Displacement/Total \ Time[/tex]
According to the question, the given values are :
Distance, d = 350 km
Time, t = 150 minutes or
t = 2.5 hours.
Average Speed = 350/2.5
Average speed = 140 km/hr
Hence, the average speed of the bus will be 140 km/hr.

A child pulls a balloon for 12m with a force of 1.0N at an angle 60 degrees below horizontal.How much work does the child do on the balloon?
Answer:
Distance for which the balloon has been pulled by the child = 12 meter
Force applied by the child to pull the balloon = 1.0 Newton
The angle below horizontal = 60 degree
These information's are already given in the question. Based on the above information's the answer to the question can be easily determined.
We know that
Work done = Force * Distance * Cos(60)
= 1 * 12 * (1/2)
= 1 * 6
= 6 Joules
So the work done by the child is 6 joules. I hope the procedure is clear enough for you to understand. Based on the above mentioned procedure, you can always solve problems of similar kind without taking any outside help.
