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 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 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 ground with speed u at an angle alpha with horizontal. It collides with a wall at a distance a from the point of projection and returns to its original position. Find the coefficient of restitution between the ball and the wall.

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 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?

A ball is thrown from the ground with a velocity of 20sqrt3 m/s making an angle of 60^@ with the horizontal. The ball will be at a height of 40 m from the ground after a time t equal to (g=10 ms^(-2))
