Question

An Object moving at a velocity of 30 m/s slows to a stop in 7 seconds. What was its acceleration

Answer 1

The answer is 4.29 m/s²

Step-by-step explanation:

The acceleration of an object given it's velocity and time taken acting on it can be found by using the formula

`acceleration = (velocity)/(time) \\`

From the question

velocity = 30 m/s

time = 7 s

We have

`acceleration = (30)/(7) \\ = 4.285714...`

We have the final answer as

4.29 m/s²

Hope this helps you
