A block of mass 0.50 kg is moving with a speed of 2.00 m/s on a smooth surface. It strikes another mass of 1.00 kg and then they move together as a single body. The energy loss during the collision is

Dear vipin


doing conservation of momentum


new  v = 0.5*2/1+0.5


 = 1/1.5 =2/3


energy loss = k.e final-k.e initila


= 0.5(1.5*(0.66*0.66) - 0.5*2*2)


= -0.6666


therefore energyloss = 0.6666n-m



Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly.

All the best.

Dear Vipin,


We know that momentum should be conserved


gives 0.5*2 = (1+0.5)*v


where v i the velocity of entire mass system moving after collision...


v=(1/1.5) m/s


energy lost = kinetic energy of the system before collision - kinetic energy of the system aftr collision


                 = 1/2*0.5*22 -1/2* 1.5 *(1/1.5)2


                 =0.6667 Joules


All the best for IITJEE preparation,
