A 0.60 kg cue ball (A) travelling at 1.5 m/s collides with a 0.50 kg numbered ball (B) which is at rest.  After the collision, the numbered ball travels at θN30° from the horizontal and the cue ball travels at θC=55º from the horizontal.  Determine the after collision velocity of the numbered ball.

An pickup truck with mass 1.85  103 kg is traveling eastbound at +14.7 m/s, while a compact car with mass 8.55  102 kg is traveling westbound at -14.7 m/s. (See figure.) The vehicles collide head-on, becoming entangled. (a) Find the speed of the entangled vehicles after the collision. (b) Find the change in the velocity of each vehicle. Δvtruck= ? m/s Δvcar= ? m/s

A cue ball of mass m1 = 0.365 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 = 5.5 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?

In the figure, projectile particle 1 is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle 0₁ = 72.2° and the oxygen nucleus recoils with speed 1.60 x 105 m/s and at angle 0₂ = 47.0°. In atomic mass units, the mass of the alpha particle is 4.00 u and the mass of the oxygen nucleus is 16.0 u. What are the (a) final and (b) initial speeds of the alpha particle? m₁ Đ Vli m₂ 0₁ Vof x

Two identical pucks collide on an air hockey table. One puck starts at rest. The incoming puck has a speed of 6.00 m/s and scatters to an angle of 30.0º. Use the fact that Θ1 – Θ2 = 90º for elastic collisions of objects that have identical masses — in other words, the pucks move apart at a right angle. (a) Sketch the collision, with angles labeled. (b) What is the velocity (magnitude and direction) of the second puck after it is struck?

In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.11 kg) and embeds itself in block 2 (mass 1.62 kg). The blocks end up with speeds v₁ = 0.600 m/s and v₂ = 1.50 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1. Frictionless (a) Number (b) Number Units Units (1) (2)

Question A puck with mass ma= 0.00242 kg moves eastward with speed  va= 1.73 m/s . It then collides with another puck of mass mb= 0.00125 kg and is moving northward with a speed vb = 2.26 m/s After the collision, puck A now moves at 48. 0° north of east, while puck B moves at 17.0° south of east.   A. What are the speeds of the two pucks after collision?

The two collars have the masses and initial velocities shown in the figure. The coefficient of restitution for the collision is e=0.5, and friction is negligible. a) Determine the velocity of the two collars after impact. b) If the time duration of the collision is 0.025 s, determine the average impact force.

A 57-kg factory worker takes a ride on a large, freely rolling 27-kg cart. The worker initially stands still on the cart, and they both move at a speed of 3.2 m/s relative to the floor. The worker then walks on the cart in the same direction as the cart is moving. The worker’s speed is now 3.8 m/s relative to the floor. What are the magnitude and direction of the final velocity of the cart?
