(b) A power hungry megalomaniac obtains mortar bomb capability. The device could fire 120.5kg mortar shells a maximum distance of 5321m when projected at 45° to the horizontal. What would the velocity of the shell be as it left the muzzle of the device?
(c) What was the maximum height reached by the shell?
S=Ut + 1/2at^2
where s=distance, u=initial velocity, a= acceleration and t=time
