A boy wants to throw a ball from a point A so as to just clear the cliff at B. The minimum horizontal velocity with which the boy should throw the ball in m/s is ſtake g = 10 m/s2]

A boy throws a ball with a velocity of 15 m/s at an angle of 15° with the horizontal. The distance at which the ball strikes the ground is

A boy can throw a stone up to a maximum height of 10 m. The maximum horizontal distance that the boy can throw the same stone up to will be:

A boy can throw a stone up to a maximum height of 10 m . The maximum horizontal distance that the boy can throw the same stone up to will be :

A boy can throw a stone up to a maximum height of 10 m . The maximum horizontal distance that the boy can throw the same stone up to will be :

A boy throws balls into air at regular interval of 2 second. The next ball is thrown when the velocity of first ball is zero. How high do the ball rise above his hand? [Take g=9.8m//s^(2) ]

A ball is projected for maximum range with speed 20 ms^-1 . A boy is located at a distance 25 m from point of throwing start run to catch the ball at the time when the ball was projected. Find the speed of the boy so that he can catch the ball (Take g = 10 ms^-1) .

A body throws a ball from shoulder height at an initial velocity of 30 m/s. Spending 4.8 s in air, the ball is caught by another boy as the same shoulder-height level. What is the angle of projection ?

A boy throws a ball with a velocity u at an angle theta with the horizontal. At the same instant he starts running with uniform velocity to catch the ball before it hits the ground. To achieve this he should run with a velocity of

A ball is throw vertically upward. It has a speed of 10 m//s when it has reached on half of its maximum height. How high does the ball rise ? (Taking g = 10 m//s^2 ).

Two rings are suspended from the points A and B on the ceiling of a room with the help of strings of length 1.2 m each as shown. The points A and B are separated from each other by a distance AB = 1.2 m. A boy standing on the floor throws a small ball so that it passes through the two rings whose diameter is slightly greater than the ball. At the moment when the boy throws the ball, his hand is at a height of 1.0 m above the floor. A stop watch which is switched on at the moment of throwing the ball reads 0.2 s when the ball passes through the first ring and 0.6 s when it passes through the second ring. The projection speed of the ball is:
