Question

Calculate the velocity of an object moving with acceleration 20 m per second square for 5 seconds if it starts from rest

Answer 1

If a particle starts from rest then it's initial velocity, U=0

Given: acceleration a= 20m/s^2

Time t= 5 sec

Velocity v=?

We know, v= u + at

V= 0 + 20 × 5 (m/s^2 × s)

V= 100 m/s
