Suppose your gun has a muzzle speed of 10 m/s. You fire it horizontally off of a 25 m cliff. How far will the bullet go horizontally before hitting the ground? How long will it take?

2. You fire a ball straight up 4 times and get these 4 heights: 1.01 m,1.05 m,0.95 m, and 0.96 m. What is the standard deviation in the height? Using the same technique as in the lab, find (a) the average muzzle speed, and (b) the uncertainty in the muzzle speed.

3. You fire a ball straight up and it reaches a height of 2.5 m. You then fire it horizontally off of a 1.5 m counter. How long will it take the ball to hit the ground?
