A ball is shot in a long hall having a roof at a height of 15 cm with speed of 25 m/s at angle of `53^(@)` with the floor. The ball lands on the floor at a distance shown x=____ m form the point of projection .

A ball is shot in a long hall having a roof at a height of 10m with 25m//s at an angle of 37^(@) with the floor. The ball lands on the floor at a distance of ………………….. from the point of projection. ( Assume elastic collisions if any )

A ball is projected form top of a tower with a velocity of 5m//s at an angle of 53^(@) to horizontal. Its speed when it is at a height of 0.45m from the point of projection is:

A ball is projected from a point on the floor wilth a speed of 15 m/s at an angle of 60^0 with the horizontal. Will ilt hit a vertical wall 5 m away from the point of projection and perpendiculaer to the plane of projection without and perpendicular to the plane of projection without hitting the floor? will the answer differ if the wall is 22 m away?

A ball is projected from the floor of a cabin of height 7m with speed 20 m/s at an angle of 37^(@) with the floor of cabin. It makes a successive collision with the wall of cabin and then return again to its floor. Assume all collisions are perfectly elastic. Find time taken (in sec) by the ball to reach the floor after collisions with the ceiling of cabin.

A particle is projected from a horizontal floor with speed 10 m//s at an angle 30^(@) with the floor and striking the floor after sometime. State which is correct.

A ball is projected from ground with a speed of 20ms^(-1) at an angle of 45^(@) with horizontal.There is a wall of 25m height at a distance of 10m from the projection point. The ball will hit the wall at a height of

A particle is projected from a horizontal floor with speed 10(m)/(s) at an angle 30^@ with the floor and striking the floor after sometime. State which is correct.

A ball is projected from ground with a speed 70m//s at an angle 45^(@) with the vertical so that it strikes a vertical wall at horizontal distance (490)/(3)m from the point of projection. If the ball returns back to the poin tof projection without any collision with ground then find the coefficient of restitution between the ball and wall.

A ball is projected from the floor of a long hall having a roof height of H = 10 m . The ball is projected with a velocity of u = 25 ms^(–1) making an angle of theta = 37^(@) to the horizontal. On hitting the roof the ball loses its entire vertical component of velocity but there is no change in the horizontal component of its velocity. The ball was projected from point A and its hits the floor at B. Find distance AB.

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m//s^(-1) at an angle of 30^(@) with the horizontal. How far from the throwing point will the ball be at a height of 10 m from the ground?
