10. An object (A) of mass mA = 17.5 kg is moving due west with a speed VA = 8.10 m/s, while object (B) of mass mg 28.0 kg is moving in a direction that makes angle of 46° south of west with a speed VB = 5.15 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision. m/s

Hockey puck A slides along a sheet of frictionless ice, moving due east with speed 2.80 m/s. It then collides with hockey puck B, which is initially at rest. After the collision, puck A is moving in a direction 30.0° north of east with a speed of 2.10 m/s. The masses of the hockey pucks are ma = 1.20 kg and mB = 1.40 kg. Apply conservation of linear momentum to the puck A+B system to find the final speed (in units of m/s) and direction of travel (in units of degrees) of puck B. 2.10 m/s 2.80 m/s A 30.0° before after collision collision

1. A 0.0850-kg bullet is fired at a stationary tin can whose mass is 0.215 kg. The bullet passes through the can, exiting the back of the can with a speed of 22.5 m/s. If the speed of the bullet is 99.0 m/s before it hits the can, what is the speed of the can after the collision?

A car of mass mg 1000 kg traveling toward the east with a speed of 10 m/s suddenly collides with a truck of mass m2 = 3000kg traveling toward the south with a speed of 20 m/s. The two vehicles stick together after the collision. Write down the conservation of momentum equation in the y-direction and cross out the terms equal to zero. m1 vliy + m2 v2iy (m1 + m Y What is the y-component of the velocity of the vehicles after the collision?

A mass of 2.71 kg is traveling in the +x direction with velocity 5.60 m/s. It collides with a stationary mass of 4.32 kg and the collision is elastic. What is the velocity of the 4.32 kg mass after the collision in m/s?

A cue ball of mass m1 = 0.305 kg is shot at another billiard ball, with mass m2 = 0.595 kg, which is at rest. The cue ball has an initial speed of v = 7.5 m/s in the positive direction. Assume that the collision is elastic and exactly head-on.  Write an expression for the horizontal component of the billiard ball's velocity, v2f, after the collision, in terms of the other variables of the problem. What is this velocity, in meters per second? Write an expression for the horizontal component of the cue ball's velocity, v1f, after the collision. What is the horizontal component of the cue ball's final velocity, in meters per second?

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 21 m/s. The masses of the two objects are 2.7 and 7.8 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 =

An inelastic collision occurs between a particle of mass 1.5 kg moving with an initial velocity of v = (−2ˆi − 1.3ˆj + 0.7kˆ) m/s and another particle of mass 0.8 kg that has an initial velocity of v = (5.6ˆi + 0.5ˆj + 4.3kˆ) m/s. What is the final velocity of the particles in unit vector notation?

Consider two objects on a collision course. Object 1 has a mass of (35 kg) and is initially moving with a velocity of (3 m/s ˆx). Object 2 has a mass of (22 kg) and is initially moving with a velocity of (5 m/s -ˆx).a) If the objects collide inelastically and stick together, what is their post-collision speed?b) If the collision occurs over a time of (0.05 s), what is the force that the objects experienced?c) If the objects instead collided elastically, what is the final speed of each object?
