A body falls freely from a point A and passes through the points B and C. Given that AB = 2BC. The ratio of the time taken by the body to cover the distances AB andBC,i

Two particles A and B are dropped from the height of 5 m and 20 m respectively. Then the ratio of time taken by A to that taken by B, to reach the ground is

A particle is projected from the top of tower 5 m high and at the same moment another particle is projected upward from the bottom of the tower with a speed of 10 m/s, meet at distance ‘h’ from the top of tower, then h

A particle was dropped from the top of the tower of height h and at the same time another partide is thrown vertically upwards from the bottom of the tower with such a velocity that it can just reach the top of the tower. The two particles meet at a height

A stone is dropped from an aeroplane which is rising with acceleration f and t seconds after this another stone is dropped. The distance between the two stones at time T after the second stone is dropped is

A stone is dropped slowly from the top of the wall and it reaches the surface of the water with the velocity 3924 cm/sec, if sound of splash is heard after 4 109/475 seconds, then the velocity of sound will he

A body falling from rest under gravity passes a certain point P. It was at a distance of 400 m from P, 4 second prior to passing through P. If g = 10 m/s², then the height above the point P from where the body began to fall is

A man on a lift ascending with an acceleration f m/sec² throws a ball vertically upwards with a velocity of v m/sec relative to the lift and catches it again in t seconds. The value of t is

A body weighs most

A cricket ball of mass 200 gm moving with a velocity of 20 m/sec is brought to rest by a player in 0.1 sec. The average force applied by the player is
