A man is walking on a road with a velocity 3 km/h. Suddenly rain starts falling. The velocity of rain is 10 km/h in vertically downward direction. The relative velocity of rain is

√13 km/h

√109 km/h

√7 km/h

13 km/h

A body covers 26, 28, 30, 32 metres in 10^th , 11^th , 12^th and 13^th seconds respectively. The body starts

from rest and moves with uniform velocity

from rest and moves with uniform acceleration

with an initial velocity and moves with uniform acceleration

with an initial velocity and moves with uniform velocity.

A body A starts from rest with an acceleration a₁ After two seconds, another body B starts from rest with an acceleration a₂ If they travel equal distances in the 5th second after the start of A, then the ratio of a₁ / a₂ is equal to

5:9

9:5

5:7

7:5

Body A is released from rest at the top of a smooth inclined plane of length 1 and at the same instant, body B is projected upward from the foot of the plane with such velocity that they meet half way up the plane. The velocity of projection of body B when 'h' is vertical height is

√gh

√2gh

√2gl

√gl

Which graph represents a uniform motion?

Which one of the following represents the time-displacement graph of two objects A and B moving with zero relative speed

When 2 bodies move uniformly towards each other, the distance between them decreases by 6 m/s. If both bodies move in the same direction with the same speeds (as above), the distance between them increases by 4 m/s. Then the speeds of the two bodies are:

4 m/s, 2 m/s

5 m/s, 1 m/s

3 m/s, 7 m/s

3 m/s, 3 m/s

An open elevator is ascending with constant speed of 10ms^-1. A ball is thrown vertically up by a boy on the elevator when it is at a height of 40 m from the ground. The velocity of projection with respect to the elevator is 30ms^-1. The maximum height attained by the ball is (take g = 10ms^-2)

85 m

60 m

120 m

45 m

A particle of mass 2 kg moving with a constant acceleration covers a distance of 10 m in the third second and 16 m in the 4th second. The initial velocity of the particle is

- 5m / s

6 m/s

10 m/s

8 m/s.

A balloon is going upwards with velocity 12 m/sec. It releases a packet when it is at a height of 65 m from the ground. How much time the packet will take to reach the ground if g = 10m/s2
