Question

A car accelerates at a rate of 5m s-2.Find the increase in its velocity in 2s.

Answer 1

Hey !!!!

_______________________

Acceleration : Velocity/Time

Acceleration : 5m/s^2

Acceleration×Time : Velocity

5m/s^2 × 2s : Velocity

10m/s : Velocity

Hence, Increase in Velocity =10m/s

Answer 2

Acceleration=Velocity/time
A=5m/s^2/2
Therefore,
Velocity =Acceleration*time
Velocity=5*2=10m/s
