Question

. Write the equations of motion and do at least 10 numerical problems based on
them.​

Answer 1

Hii frnd .. three equations of motion are :

1:)v=u+at

2:)s=ut+1/2at^2

3:)v^2=u^2-2as

where

v=final velocity

u=initial velocity

t=time

a=acceleration

s=distance

Question 1

A train accelerates from 36 km/h to 54 km/h in 10 sec. Find

(i) Acceleration

(ii) The distance travelled by car.

Answer a=.2 m/s2

b) s=125m

Question 2

A body whose speed is constant

(a) Must be accelerated

(b) Might be accelerated

(c) Has a constant velocity

(d) Cannot be accelerated.

Question 3

A truck traveling at 54 km/h is slow down to 36 km/h in 10 sec. Find the retardation.
