A cricket ball is thrown at a speed of 30 m s^(-1) in a direction 30^(@) above the horizontal. The time taken by the ball to return to the same level is

A cricket ball is thrown at a speed of 28 m s^(-1) in a direction 30^(@) above the horinzontal . Calculate its maximum height.

A cricket ball is thrown at a speed of 28 ms^(-1) in a direction 30 ^(@) above the horizontal. Calculate (a)the maximum height (b) the time taken by ball to return ti the same level, and (c )the distance from the thrower to the point wher the ball restance from the throwrt to the point where the ball returns to the same level.

An object is being thrown at a speed of 20 m/s in a direction 45^(@) above the horizontal . The time taken by the object to return to the same level is

A platform is moving upwards with an accelerations of 5ms^(-2) . At the moment when its velocity is u = 3ms^(-1) , a ball is thrown from it with a speed of 30 ms^(-1) w.r.t. platform at an angle of theta = 30^@ with horizontal. The time taken by the ball to return to the platform is

From the top of a tower of height 40m, a ball is projected upward with a speed of 20ms^(-1) at an angle of elevation of 30^(@) . Then the ratio of the total time taken by the ball to hit the ground to the time taken to ball come at same level as top of tower.

A ball is thrown straight upward with a speed v from a point h meter above the ground. The time taken for the ball to strike the ground is
