A boy decides to toss a rock over a cliff. If the mass of the rock is 0.5 kg and he tosses it horizontally with a velocity of 10 m/s, how long will it take the rock to hit the water if the cliff where he is standing is 175 m above the ocean? What is the magnitude of its velocity when it hits?

A physics student stands on a cliff overlooking a lake and decides to throw a golf ball to her friends in the water below. She throws the golf ball with a velocity of 18.5 m/s at an angle of 37.5∘ above the horizontal. When the golf ball leaves her hand, it is 10.5 mabove the water. How far does the golf ball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer.
