Question

What is the acceleration of a car moving at 36 km/h coming back to rest in 10 seconds?

Answer 1

Answer:

Initial velocity (u) :- 36 km/h = 36×5/18= 10m/s

time (t) :- 10 sec

final velocity :- 0 m/s

acceleration = v-u/t

10-0/10

1 m/s^2

Hence, acceleration is 1 m/s^2

Answer 2

Explanation:

Given:-

Velocity =36km/h

=36000m/3600sec

=10m/s

Time=10 sec

Acceleration:-Velocity /Time

So,here acceleration =10/10

=1 m/sec square
