A player kicks a football of mass `0.5` kg and the football begins to move with a velocity of 10 m/s . If the contact between the leg and the football lasts for `(1)/(50)`sec , then the force acted on the football should be

A football player kicks a 0.25 kg ball and imparts it a velocity of 10 m/s. The contact between foot and the ball is only (1)/(50)th of a second. The kicking force is

A football player kicks a 0.25 kg ball and imparts it a velocity of 10 m/s. The contact between foot and the ball is only (1)/(50)th of a second. The kicking force is

A ball of mass 0.2 kg moves with a velocity of 20m//sec and it stops in 0.1 sec , then the force on the ball is

A ball of mass 0.2 kg moves with a velocity of 20m//sec and it stops in 0.1 sec , then the force on the ball is

A ball of mass 0.2 kg moves with a velocity of 20m//sec and it stops in 0.1 sec , then the force on the ball is

A player stops a football weighing 0.5 kg which comes flying towards him with a velocity of 10m//s . If the impact lasts for 1//50 th sec. and the ball bounces back with a velocity of 15 m//s , then the average force involved is

A football player kicks a 0.8 kg ball and imparts it a velocity 12 ms^(-1) the contact between the foot and ball is only for one sixtieth of a second find the average kicking force
