Question

A scooter travelling at 10 m/s speed up to 20 m/s in 4 sec. Find the acceleration of train. ​

Answer 1

the initial velocity is 10 meter per sec.
the final velocity is 20 meter per sec.
the time is 4 sec.
the acceleration is v-u/t
20-10/4
=2.5m/sec2


U

Answer 2

Initial Velocity(U) = 10 m/s

Final Velocity(V) = 20 m/s

Time( t ) = 4 sec

Acceleration = V - U/ T

So , A = 20 m/s - 10 m/s / 4 sec

A = 10 m/s / 4 sec

A = 2.5 m/s^2
