Find parametric equations for the shell''s trajectory

Reference no: EM137852

Q1. A shell, fired from a cannon, has a muzzle speed (the speed as it leaves the barrel) of 800 ft/s. The barrel makes an angle of 45o with the horizontal and, for ease; the barrel opening is assumed to be at ground level.

(a) Find parametric equations for the shell's trajectory relative to the coordinate system

(b) How high does shell rise?

(d) What is the speed of shell at its point of impact with the ground?

Q2. A uniform horizontal bar of length L = 3 m and weight 226 N is pinned to a vertical wall and supported by a thin wire that makes an angle of theta = 20o with the horizontal. A mass M, with a weight of 347 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 596 N. What is the most possible distance from the wall at which mass M can be placed before the wire breaks?
