A man is riding on a flat car travelling with a constant speed of `10m//s`.He wishes to throw a ball through a stationary hoop `5 m` above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of `12.5 m//s` w.r.t himself.
How many seconds after he release the ball will it pass through the hoop?

A man is riding on a flat car travelling with a constant speed of 10m//s .He wishes to throw a ball through a stationary hoop 15 m above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of 12.5 m//s w.r.t himself. At what horizontal distance in front of the hoop must he release the ball?

A man is standing on a rail road car travelling with a constant speed of v = 10 ms^-1 (Fig . 5.34). He wishes to throw a ball through a stationary hoop 5 m above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of 12.5 ms^-1 w.r.t. himself. (a) What must be the vertical component of the initial velocity of the ball ? (b) How many seconds after he releases the ball will it pass through the hoop ? ( c) At what horizontal distance in front of the loop must he release the ball ? .

A boy throws a ball in air in such a manner that when the ball is at its maximum height he throws another ball. If the balls are thrown with the time difference 1 second, the maximum height attained by each ball is

A man thrown a ball making an angle of 60^(@) with the horizontal.He runs on a level ground with constant velocity and catches the ball at the same horizontal level as it was thrown.If he had thrown the ball with speed 4m/s, then speed of running must be ?(in m/s)

A billiard ball moving with a speed of 5 m//s collides with an identical ball, originally at rest. If the first ball stop dead after collision, then the second ball will move forward with a speed of:

A highly elastic ball moving at a speed of 3 m//s approaches a wall moving towards it with a speed of 3 m//s . After the collision. the speed of the ball will be

A cricketer can throw a ball to a maximum horizontal distance of 100 m. How high above the ground can the cricketer throw the ball, with the same speed ?

A boy is standing inside a train moving with a constant velocity of magnitude 10 m/s. He throws a ball vertically up with a speed 5 m/s relative to the train. Find the radius of curvature of the path of the L ball just at the time of projection.
