A projectile (a stale doughnut for instance) is launched with a speed of 50.0 m/s and an angle of 35.2 degrees above the horizontal, from the top of a 75.0 m high cliff onto a flat valley floor at the base of the cliff. (a) How long (s) does it take the projectile to reach the valley floor? (b) What is the horizontal distance (m) between the base of the cliff and the impact point? What is the (c) vertical (m/s) component of the velocity just before impact? What is the (d) horizontal (m/s) component of the velocity just before impact?
