An object with mass m and speed v explodes into two pieces, one three times as massive as the other; the explosion takes place in gravity-free space. The less massive piece comes to rest. How much kinetic energy was added to the system?Kinetic Energy of an object when it explodes?
(1/4)mv1 = (3/4)m(v2 - v1)
v1 = 3v2 - 3v1
v2 = (4/3)v1
鈭咾E = (1/2)mv1^2[(3/4)(4/3)^2 - 1]
鈭咾E = (1/3)KE1Kinetic Energy of an object when it explodes?
