Q1. Shell, fired from a cannon, has a muzzle speed (speed as it leaves the barrel) of 800 ft/s. The barrel makes an angle of 45o with the horizontal and, for simplicity; barrel opening is supposed to be at ground level.
(a) Find out parametric equations for the shell's trajectory relative to the coordinate system.
(b) How high does shell rise?
(c) How far does the shell travel horizontally?
(d) What is speed of the shell at its point of impact with the ground?
