Question

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

(a) ANSWER:

==============================

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

During collision momentum is conserved

Initial momentum = Final momentum

(b) ANSWER:

==============================
