1- During a fireworks display, a shell is shot into the air at an angle of X degrees above the horizontal. The fuse is timed so that the shell explodes after 8,9 seconds, just as it reaches its highest point above the ground. If the horizontal displacement of the shell is 50,5 meters when it explodes, what is the angle X of the initial velocity? Use g = 9.8 m/s 2- A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a ramp of 34,3 degrees at a speed of 25,8 m/s. How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 10.0 m long? Use g = 9.8 m/S 3- A rock is eiected from the Kilauea volcano with a speed of 7,7 m/s and at 6,0 degrees above the horizontal. The rock strikes the side of the volcano at an altitude 7,7 meters lower than its starting point. Calculate the magnitude of the rock's velocity at impact. Use g = 9.8 m/S
