1. Lirio is exerting a force of 89 N on a nice boulder in her swamp. The nice boulder is 68 kg. What is the acceleration of the nice boulder? 2. If Renae has a mass of 85 kg, and you exert a force of 45N on her, what would her acceleration be?

CAN I PLEASE GET HEPL ON THESE 2 I NEED TO KNOW THE EQUATIONS!!!

Step-by-step explanation:

1.

F=ma

89=68a

a=89/69 units/s²

2.F=ma

45=85 a

a=45/85=9/17 units/s²

Problem 1

Approximately 1.3 m/s^2

Work Shown:

We'll use the formula F = m*a, which is from Newton's second law.

The force applied is F = 89 newtons. The mass of the boulder is m = 69 kilograms. This means,

F = ma

89 = 69*a

a = 89/69

a = 1.28985507246377

a = 1.3

I rounded to 2 sig figs because the other given values (89 and 69) are to 2 sig figs as well.

Problem 2

Approximately 0.53 m/s^2

Work Shown:

We'll follow the same idea as problem 1

This time we are given F = 45 and m = 85

So,

F = ma

45 = 85*a

85a = 45

a = 45/85

a = 0.52941176470589

a = 0.53

The acceleration is roughly 0.53 m/s^2, which means that for every second, the speed is increasing by roughly 0.53 m/s.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
