An aluminum ball is shot from a cannon. As it leaves the muzzle of the cannon, the ball has a temperature of 100oC and a velocity of 250 m/s. Experiencing no air resistance, the ball hits a target and drops to a velocity of 0. Assuming that there is no heat lost in the process, what is the temperature of the aluminum ball after the ball comes to rest?
Given: Al; T1 = 100oC; V1 = 250 m/s; V2 = 0 Assume: Q = W = ?PE = 0; the Aluminum is an incompressible substance with constant specific heats: c = 0.903 kJ/kg-K = 903 J/kg-K What will be an ideal response?
