A car acceletrates uniformaly at `4 m s^(-2)` froms rest. Find its velocity at the end of 5 seconds.

Text Solution

Verified by Experts

Given acceleration of the car, `a=4 m s^(-2)`
Initial velocitt of the car,` u=0 m s^(-1)`
Time interval, t=5s
Final velocity of the car,` v=u+at`
`=0+(4)(5)`
`=20 m s^(-1)`
