Question

A cart rolling at a speed of 10 m/s comes to a stop in 2s. What is the cart's acceleration?

Answer 1

the acceleration is 5m/s

Step-by-step explanation:

Answer 2

The cart´s acceleration is 5
`(m)/(s^(2) )`

Step-by-step explanation:

Considering that this is a case of linear motion, apply the formula described below:

`(v_(1)-v_(0)  )/(t) =`
`( 10(m)/(s) - 0(m)/(s) )/(2s)`

The formula has been written by replacing the following:

v1=10m/s, v0=0 and t=2s
