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.]
A copper telephone wire has essentially no sag between poles 20.5 meters apart on a winter day while the temperature is -15.5° C. How much longer is the wire on the summer day when the temperature is 27.0° C.

A 200, 47.0 cm-diameter turntables rotate on frictionless bearings at 70. A 24.0 block sits at the center of the turntable. A compressed spring shoots the block radically outward along the frictionless groove in the surface of turntable.
A mass of 1.60 kg stretches a vertical spring 0.335 m. If the spring is stretched an additional 0.164 m and released, how long does it take to reach the (new) equilibrium position again.
A ranger in a national park is driving at 52 km/h when a deer jumps onto the road 86 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -2.9 m/s2.
