Question

A car starts with an initial velocity of 10 mns and
accelerates at a rate of 5 m s? Find the final velocity
when the car has travelled a distance of 30 m. What
time has been taken by the car for this motion?​

Answer 1

Answer:

Initial Velocity (u) = 10 m/sec

Acceleration (a) = 5 m/sec

2

Distance (s) = 30 m

Final velocity (v) = ??

Using Newton's Third law of Motion,

v
