Question

A scooter acquires a velocity of 36km per hour in 10sec.it starts from rest.calculate the acceleration of the scooter

Answer 1

Answer:

1m/s2

Explanation:

First we convert 36 km/h to m/sec

1 km = 1000m

36 km = 36×1000m

36km = 36000m

Also 1h = 60m

= 60 × 60 seconds

= 3600sec

So

36 km/ hour = 36000/3600 m/s

= 10m/s

Thus the velocity is 10m/s

Now,

Initial velocity = 0

Final velocity = 10m/ s

and time = t

then

by 2nd equation of motion,

v = u+ at

we get :- 10= 0 + a× 10

10a =10

a = 10/10

a = 1m/s2
