What is the highest point he reaches above the water

Reference no: EM138950

Q1. A cannonball shot with the initial velocity of 129 m/s at an angle of 36° follows a parabolic path and hits a balloon at the top of its trajectory. Neglect air resistance, how fast is the cannonball going as it hits the balloon?

Q2. A diver springs upward with an initial speed of 2.0 m/s from a 4.0 m board.

(a) Find out the velocity with that he strikes the water. (Hint: When the diver reaches water, his displacement is y = -4.0 m (measured from the board), assume that the downward direction is selected as the negative direction.)

(b) What is the highest point he reaches above the water?
