A ball is projected from ground with a velocity `V` at an angle `theta` to the vertical. On its path it makes an elastic collison with a vertical wall and returns to ground. The total time of flight of the ball is

A ball is projected from the ground with velocity u such that its range is maximum Then

A ball of mass m is projected from the ground with an initial velocity u making an angle of theta with the vertical. What is the change in velocity between the point of projection and the highest point ?

A ball of mass m is projected from the ground with an initial velocity u making an angle of theta with the vertical. What is the change in velocity between the point of projection and the highest point ?

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 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 top of a tower at an angle 60^(@) with the vertical. What happens to the vertical component of its velocity?

A ball is projected towards right from point A at an angle theta with vertical. A system imparts an acceleration g tan theta to the ball towards left along negative x-axis. The ball will return to ground at :

A ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at some distance from the point of projection and returns on the same level. Coefficient of restitution between the ball and the wall is e, then time taken in path AB and maximum height attained by the ball is
