An object starting from rest travels 20 m in first 2 s and 160 m in next 4 s.
What will be the velocity after 7 s from the start.
An object is dropped from rest at a height of 150 m and simultaneously
another object is dropped from rest at a height 100 m. What is the difference
in their heights after 2 s if both the objects drop with same accelerations?
How does the difference in heights vary with time?
Draw a velocity versus time graph of a stone thrown vertically upwards
and then coming downwards after attaining the maximum height.
The displacement of a moving object in a given interval of time is zero.
Would the distance travelled by the object also be zero? Justify you answer
In which of the following cases of motions, the distance moved and the
magnitude of displacement are equal?
(a) If the car is moving on straight road
(b) If the car is moving in circular path
(c) The pendulum is moving to and fro
(d) The earth is revolving around the Sun

Slope of a velocity – time graph gives
(a) the distance
(b) the displacement
(c) the acceleration
(d) the speed
Suppose a boy is enjoying a ride on a merry-go-round which is moving
with a constant speed of 10 m s–1. It implies that the boy is
(a) at rest
(b) moving with no acceleration
(c) in accelerated motion
(d) moving with uniform velocity
