A projectile, thrown with velocity `v_(0)` at an angle `alpha` to the horizontal, has a range R. it will strike a vertical wall at a distance `R//2` from the point of projection with a speed of

A projectile is thrown upward with a velocity v_(0) at an angle alpha to the horizontal. The change in velocity of the projectile when it strikes the same horizontal plane is

A projectile is thrown upward with a velocity v_(0) at an angle alpha to the horizontal. The change in velocity of the projectile when it strikes the same horizontal plane is

A projectile is thrown with a velocity u_(0) at an angle theta with the horizontal. The ratio of the rate of change of speed w.r.t. time, at highest point to that at the point of projection, is

A ball is projected at t = 0 with velocity v_0 at angle theta with horizontal. It strikes a smooth wall at a distance from it and then falls at a distance d from the wall. Coefficient of restitution is 'e' then :

A javelin is thrown with an initial velocity v_0 at an angle theta with the horizontal. What is the horizontal and vertical velocities of the body I) at the point of projection II) at maximum height

A projectile thrown with an initial speed u and the angle of projection 15^@ to the horizontal has a range R . If the same projectile is thrown at an angle of 45^@ to the horizontal with speed 2 u , what will be its range ?
