Projectile motion worksheet with answers
A ball is launched horizontally from the top of a 60 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.
A ball is launched from level ground at 28 m/s and must land 50 m away. Ignore air resistance and use g = 9.81 m/s². Find the smaller of the two possible launch angles θ.
A ball is kicked from level ground at 32 m/s and 60° above the horizontal towards a wall 36 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?
A ball is thrown from ground level at 36 m/s and 45° above the horizontal. It lands on the flat roof of a building 8 m high, on its way down. Ignore air resistance and use g = 9.81 m/s². Find the horizontal distance x from the launch point to where it lands.
A ball is launched at 29 m/s and 40° above the horizontal from the top of a 5 m cliff. Ignore air resistance and use g = 9.81 m/s². At what angle α below the horizontal does it hit the ground?
