1. A girl throws a rock horizontally, with a velocity of 13 m/s, from a bridge. It falls 17 m to the water below. How far does the rock travel horizontally before striking the water, assuming negligible air resistance? Use g = 9.8 m/s2

2. Suppose one of Napoleon cannons has a muzzle speed of 32m/s. It was aimed at 54 ◦ angle. What height can the cannon ball reach? Use g = 9.8 m/s2

3.A car traveling 69 km/h is 247 m behind a truck traveling 93 km/h. How long will it take the car to reach the track? Calculate to one decimal
