Question

What is a cars acceleration in the direction of motion when velocity changes from 20. M/s to 60. M/s in 10. S

Answer 1

Acceleration,
`a=4\ m/s^2`

Step-by-step explanation:

Given that,

Initial velocity, u = 20 m/s

Final velocity, v = 60 m/s

Time, t = 10 s

We need to find the acceleration of the car. It is equal to the change in velocity divided by time.

`a=(v-u)/(t)\\\\a=(60-20)/(10)\\\\a=(40)/(10)\\\\a=4\ m/s^2`

So, the acceleration of the car is
`4\ m/s^2`.
