Question

Starting from rest satvik attains a velocity of 20 m/ s in 4 sec calculate the acceleration

Answer 1

Answer:

Initial Velocity = 0 m/s

Final Velocity = 20 m/s

Time = 4 sec

Acceleration = 20 - 0 / 4 = 20/4 = 5 m s^-2

Answer 2

If he started from rest ;

then u =0 m/s

t=4 seconds.

v=20m/s

Apply v=u+at

=> 20 = 0 + 4a

=> 4a = 20

=> a = 5m/sec^2
