Question

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

Answer 1

Answer:

2.5m/s square is the acceleration

Explanation:

Initial velocity (u)= 10 m/s

Final velocity (v)= 20 m/s

Time taken (t)= 4 seconds

Acceleration (a)= v-u/t

                        = 20-10/4

                         =10/4

                          =2.5m/s square

Answer 2

Answer:

final velocity =  20 m/s

starting velocity =  10m/s

time taken =  4 sec

final velocity - starting velocity / time taken

= 20 - 10 / 4

=  10 / 4

= 2.5
