A ball of mass 5.00 kg is thrown from the ground at an angle of 20.0\deg from the vertical with a speed of 20.0 m/s. The ball lands on top of a building that is 10.0 m tall. What is the speed of the ball in m/s just before it lands on the roof of the building?
An illustration of a projectile motion of a ball.A large block of length 10.0 meters stands on the surface of a plane. A ball inclined at a certain angle and with an inertia of 20.0 I and a velocity of 20.0 meters per second is thrown toward the block thereby forming a projectile in the shape of a downward open parabola.
