- "A person stands on the ground 60m away from a cliff with a height h. They throw a ball toward the cliff with a speed of vp = 30 m/s and an angle of 60° above the horizontal. It lands on top edge of the cliff some time later. How high is the cliff, and what is the ball's impact speed?"A projectile is fired from a point 50 meter from a tall cliff at 75 m/sec and at angle of 50 degrees above the horizontal. It will strike the cliff at a point h above the cliff base. What is h? What is the final speed of the projectile when it hits the cliff in the problem above?A ball is thrown at 60° with initial velocity of 10 m/s, it reaches the maximum height and on return it hit an inclined surface 2 m above the initial level and inclined at 40° and bounces back at 90° with the inclined surface, with half of the speed of impact.
