Consider a frictionless track where a 4.00-kg hollow ball is held at point A. After this ball is released, it makes a head-on perfectly inelastic collision at point B with a 12.00-kg solid ball that is initially at rest. Determine the linear speed of the system after the collision. 4.00 kg (A) 2.00 m 12.00 kg (B)

Chapter 07, Problem 30 GO 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 3.2 and 7.9 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. (a) Vf = (b) Vf =

Object 1 with a mass of 4.70 kg, moving right at a speed of 7.80 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.30 kg moving left at a speed of 10.6 m/s. After the collision, the Object 1 is moving left at 2.40 m/s.

A 4.00 g bullet travelling horizontally with a magnitude of 440 m/s is tired into a wooden block with a mass of 0.80 kg intitially st rest on a level surface. The bullet passes through the block and emerges with its speed reduced to 160 m/s. What is the speed of the block just after the bullet has passed through the block? - 14 m/s - 1.4 m/s - 3.0 m/s - 12 m/s
