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 3.6 and 8.1 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.

A 5.3 kg sphere makes a perfectly inelastic collision with a second sphere initially at rest (they stick together after the collision). The composite system moves with a speed equal to one third the original speed of the 5.3 kg sphere. What is the mass of the second sphere?

Quesitos: The drawing shows a bullet passing through two blocks that rest on a horizontal, frictionless surface. Rule out air resistance. The bullet completely passes through the first block and is buried in the second block. Notice that after the collision, both blocks move. Can the Conservation Principle be applied from Linear Momentum to this three-body system? Justify your answer (Ignore any loss of mass from the first block). Problem: A 4.00-g bullet moves horizontally with velocity of + 355m / s. The mass of the first block is 1150 g, and its velocity after the bullet passes through it it is +0.550 m / s. The mass of the second block is 1530 g. (a) Obtain the speed of the bullet after passing through the first block, (b) obtain the velocity of the second block after the bullet is buried in it

A 0.060-kgkg tennis ball, moving with a speed of 5.80 m/sm/s , has a head-on collision with a 0.090-kgkg ball initially moving in the same direction at a speed of 3.48 m/sm/s . Assume that the collision is perfectly elastic. Determine the speed of the 0.090-kgkg ball after the collision. Express your answer to two significant figures and include the appropriate units.

A 0.01 kg bullet traveling horizontally at the speed of sound (343 m/s) embeds itself into the Kevlar vest of a stationary 100 kg physics professor. The bullet and the professor then move as one. What is the speed of the bullet/professor system after the collision?

A 12 kg block, initially moving to the right, collides with a stationary 18 kg block, causing the 18 kg to move off to the right. The collision is perfectly elastic. We may conclude that after the collision, the 12 kg block will stop. move to the right with less speed than it had before the collision. move to the right with the same speed that it had before the collision. move to the left with less speed than it had before the collision. move to the left with the same speed that it had before the collision.

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 =

Two objects, A and B, with masses 3.2 kg and 1.8 kg, move in a frictionless horizontal surface. Object A moves to the right at a constant speed of 5.1 m/s while object B moves to the right at a constant speed of 1.4 m/s.  They collide and stick together. a) Find the total kinetic energy of the system after the collision. b) Is the kinetic energy of the system conserved?  Explain.

Need help checking a practice problem. Thanks!

INITIAL: FINAL: M. A white billiard ball with mass mw = 1.53 kg is moving directly to the right with a speed of v = 3.25 m/s and collides elastically with a black billiard ball with the same mass mb = 1.53 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of ew = 51° and the black ball ends up moving at an angle below the horizontal of Ob = 39°. %3D 1) What is the final speed of the white ball? m/s Submit 2) What is the final speed of the black ball? m/s Submit
