A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of
v0 = 19.5 m/s.
The cliff is h = 56.0 m above a flat, horizontal beach as shown in the figure.
A student stands on the edge of a cliff with his hand a height h above a flat stretch of ground below the clifftop. The +x-axis extends to the right along the ground and the +y-axis extends up from the ground to the top of the cliff. The origin O of the coordinate plane is directly below the student's hand where the base of the cliff meets the flat ground. The student throws a stone horizontally rightward with initial velocity vector v0. The stone falls with a parabolic trajectory, hitting the ground with a velocity vector v that points down and right. Vector g points straight down.
(a) What are the coordinates of the initial position of the stone?

56.0 m
(b) What are the components of the initial velocity?

A physics student stands on a cliff overlooking a lake and decides to throw a softball to her friends in the water below. She throws the softball with a velocity of 22.5 m/s22.5 m/s at an angle of 39.5∘39.5∘ above the horizontal. When the softball leaves her hand, it is 15.5 m15.5 m above the water. How far does the softball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer.
A baseball player wants to hit a home run over the wall of a stadium. The player swings the baseball bat so that it hits the ball when it is at a height of 0.992 mm above the ground. The ball flies off at an angle of 30∘30∘ above the horizontal and at a speed of 35.9 m/sm/s. What is the tallest wall that the player can clear (i.e., get the ball over) if the wall is 84.2 m m away horizontally?

They ended their trip on the southbank of a 1200 m wide river, directly across from where Caroline is waiting to pick them upon the north bank.
