A 6.75-kg bowling ball moving at 8.95 m/s collides with a 0.875-kg bowling pin, which is scattered at an angle of θ = 24.5° from the initial direction of the bowling ball, with a speed of 11.2 m/s. Calculate the magnitude of the final velocity, in meters per second, of the bowling ball.

A 5.75 kg bowling ball moving at 9.20 m/s collides with a 0.860 kg bowling pin, which is scattered at an angle of 85.0° to the initial direction of the bowling ball and with a speed of 14.0 m/s. (Assume the bowling ball is initially moving in the +x-direction.) (a) Calculate the final velocity of the bowling ball.

O Yes O No (c) Linear kinetic energy is greater after the collision. Discuss how spin on the ball might be converted to linear kinetic energy in the collision.

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

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

A 3.10-kg ball, moving to the right at a velocity of +1.43 m/s on a frictionless table, collides head-on with a stationary 8.60-kg ball. Find the final velocities of (a) the 3.10-kg ball and of (b) the 8.60-kg ball if the collision is elastic. (c) Find the magnitude and direction of the final velocity of the two balls if the collision is completely inelastic. (a) Number Units (b) Number Units (c) Number Units

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?

A 10 kg cannonball is fired horizontally to the left out of a 1700 kg cannon. The cannonball leaves the muzzle at −600x^ms−600x^ms. The recoil velocity of the cannon  is Answer

A cue ball at rest on a frictionless pool table is hit dead center by a pool stick, giving it an impulse of +1.85 N · s. The ball slides (the combination of hitting the ball dead center and no friction allows this to happen) along the table and makes a head-on elastic collision with another pool ball. If both pool balls have a mass of 0.156 kg, determine the velocity (in m/s) of the second ball the instant after the collision.
