Bodies stick together after collision the heat liberated, Mechanical Engineering

Assignment Help:

Two bodies of mass 1 kg and 2 kg move towards each other in mutually perpendicular direction with velocities 3m/s and 2 m/s respectively. If the bodies stick together after collision the heat liberated will be?

Ans) Total momentum before collision=7 units.

After collision M=3 so v=7/3 units,

Final energy=1/2Mv^2=49/6 J

Initial energy= 1/2m1(v1)^2 + 1/2 m2.(v2)^2

                    = 9/2+4=17/2 J

Loss in energy= initial - final=17/2 - 49/6=2/6=1/3= .33 Joules

Two bodies of mass 1 kg each move in the same direction with velocities 20 m/s and 10 m/s respectively. If the bodies stick together after collision how much heat is liberated? Would the answer change if one body was at rest and the other moving at 10 m/s ?
