Question

a scooter travelling at 10 m/s speed upto 20m/second in 4 seconds find the accelerationof train

Answer 1

Your answer is here

Initial velocity=u=10m/s

Final velocity=v=20m/s

time=t=4s

acceleration of scooter=v-u/t

=20-10/4
=10/4
=2.5m/s

The acceleration produced is 2.5m/s

hope it helps

Answer 2

acceleration =v-u/t
a=20-10/4
a=10/4
a=2.5
