Question
During a fireworks display, a shell is shot into the air with an initial speed of 70.0 m/s at an angle of 75.0º above the
horizontal, as illustrated . The fuse is timed to ignite the shell just as it reaches its highest point above the
ground. (a) Calculate the height at which the shell explodes. (b) How much time passed between the launch of the shell and
the explosion? (c) What is the horizontal displacement of the shell when it explodes?
