When brakes are applied, force absorbed by his seat belt was 870 N.
What is force?The force is an action of push or pull in order to move or stop the body.
Given is the mass m=60 kg, velocity changes from v1 =30m/s to v2= 1m/s in time t=2s.
The acceleration is the time rate of change of velocity.
a = v1 -v2 /t
a =30 -1 /2
a = 14.5 m/s²
According to the Newton's second law of motion, the force absorbed by belt was
F =ma
F =60 x 14.5
F = 870 N.
Thus, force absorbed by his seat belt was 870 N.

Explanation:
In a certain pentagon, the interior angles are $a^\circ,$ $b^\circ,$ $c^\circ,$ $d^\circ,$ and $e^\circ,$ where $a,b,c,d,e$ are integers strictly less than $180$. ("strictly less than $180$" means they are "less than and not equal to" $180$.) if the median of the interior angles is $61^\circ$ and there is only one mode, then what are the degree measures of all five angles?
The degree measures of all of these angles are 60, 61, 61, 179, 179.
How to solve for the angle measuresGiven that the 3rd largest angle that we have here is 61 degrees, the three angles are not going to be more than 183.
The sum of all the angles must be 540 degrees. The total of the largest of the numbers is less that 179 x 2 = 358 degrees.
The sum of the smallest three would be
540 - 358 = 182 degrees
Therefore the possible sets of these angles would be 60, 61, 61, 179, 179 degrees

#SPJ1
Answer:
61, 61, 61, 178, 179
Explanation:
The five interior angles of any pentagon add up to 3*180= 540
If the median is 61, then we know the three smallest angles are each no more than 61, and so they add up to at most 3*61= 183 degrees. This means the two largest angles must add up to at least 540-183= 357 degrees. Since 178+179=357, and since the angles are all integers strictly less than 180, the only possibilities for the two largest angles are 178, 179 or 179, 179.
We consider these possibilities one at a time.
If the two largest angles are 178 and 179, then the three smallest angles add up to exactly 183, so they must each be exactly 61. Thus, one set of angles that satisfy the conditions in the problem is 61, 61, 61, 178, 179.
If the two largest angles are 179 and 179, then the three smallest angles add up to 182. The only way this can happen is for one of them to be 60 and the other two to be 61, but in this case, the set of angles would have more than one mode. So we can rule out this answer.
In conclusion, the five angles must be 61, 61, 61, 178, 179.

Answer: is C) and D) cuz ayshagibson said so....
Explanation:
The central ideas of this excerpt were that "The mistakes men make are remembered after their deaths, but their good deeds more often die with them" and that "If Caesar was power-hungry, it was a serious flaw, and he paid seriously for it".
Who spoke about Caesar?Here, Anthony spoke about Caesar. It was written that the evils that people do will live after them even when they die. On the other hand, their good deeds will be forgotten. Also, if Caesar was power-hungry, it was a serious flaw, and he paid seriously for it. Anthony spoke I'll about him.
Antony who was unhappy at the death of Ceasar and who swore to avenge his death, in the speech above, remarked that the accusations made by Brutus and others against Caesar did not take into account his good deeds while alive.
Thus, he implied that people tend to forget the good deeds of others when they die but only recall their bad deeds. He also showed through this statement that if the accusations about Caesar being ambitious were actually true, he paid dearly for it given the way he died.

A random drawing will determine which 3 people in a group of 9 will win concert tickets. what is the probability that you and your 2 friends will win the tickets? express your answer as a fraction in simplified form.
The probability that you and your 2 friends win the tickets is P = 1/84.
How to determine the probability?
There are 9 possible outcomes, 3 of which are you and your friends.
All of these outcomes have the same probability of being randomly selected, then the probability of winning is given by the quotient between the number of "outcomes" that you have and the total number of outcomes.
Let's say that the outcomes are pieces of paper with the names of the participants.
First draw:
In this one, there are 3 possible options that work, one is your paper, and the other two are for your friends.
So the probability is 3/9 = 1/3.
Second draw.
One of your group already won, so now there are 2 of you, and a total of 8 pieces of paper, so this time the probability is 2/8 = 1/4
Final draw:
Only one of you remains, and there is a total of 7 pieces of paper, this time the probability is 1/7.
The joint probability (of these 3 events happening in succession) is given by the product of the individual probabilities:

If prices rise by 1.5% a month, by how much will they increase over a full year? input your answer correct to two decimal places.
Answer:
18% in a year
Explanation:
We know that there are 12 months in a year. To to find the percentage of yearly increase, we just need to multiply the monthly percentage by the number of months in a year.
1.5% = 0.015
0.015 * 12 = 0.18
0.18 = 18%
So, the prices increase 18% in a year.
