One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 24 m/s. The masses of the two objects are 2.3 and 7.1 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.

Answer #1

(a) when the large-mass object is the one moving initially at 24m/s

During collision momentum is conserved

Initial momentum = Final momentum

Indicate true or false in the following statements: Two particles can collide and one can leave at right angles to the other in a perfect inelastic collision. Momentum is conserved in all collisions and kinetic energy is not conserved in inelastic collisions. It is not possible for a one mass to transfer all its momentum to an identical but initially stationary mass. For a pair of colliding particles, if there was zero total momentum in the x direction before a...
