Two identical pellet guns are fired simultaneously from the, Ask an Expert

Academics

Q1. Two identical pellet guns are fired simultaneously from the edge of a cliff. These guns impart an initial speed of 24.1 m/s to each pellet. Gun A is fired straight upward, with the pellet going up and then falling back down, eventually hitting the ground beneath the cliff. Gun B is fired straight downward. In the absence of air resistance, how long after pellet B hits the ground does pellet A hit the ground?

Q2. A diver springs upward with an initial speed of 1.7m/s from a 5.0m board.

Find out the velocity with which he strikes the water. [Hint: When diver reaches the water, his displacement is y = -5.0m (measured from the board), assume that the downward direction is chosen as the negative direction.]
