Question

A rock is rolling down a hill. At position 1, its velocity is 2.0 m/s. Twelve seconds later, as it passes position 2, its velocity is 44.0 m/s. What is the acceleration of the rock?

Answer 1

Hello there,

Hope your fine .

We us the below formula:

Time = Velocity 1 - Velocity 2 / acceleration

To find the acceleration:

Acceleration = Velocity 2 - Velocity 1/ time

 The answer is 44 - 2 / 12 = 3.5 m/s

I hope you are satisfied with the answer.

Thanks

Answer 2

3.5m/s^2 and yeah i literally did this to get points for some reason dont flag btw
