A ball is projected at an angle `45^(@)` with horizontal. It passes through a wall of height `h` at horizontal distance `d_(1)` from the point of projection and strikes the ground at a horizontal distance `(d_(1) + d_(2))` from the point of projection, then

A projectile is fired at an angle of 45^(@) with the horizontal. Elevation angle of the projection at its highest point as seen from the point of projection is

A body projected from a point O at an angle theta , just crosses a wall y m high at a distance. x m from the point of projection and strikes the ground at Q beyond the wall as shown, then find height of the 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.
