A cue ball traveling at 6.47 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision. 90 ° (correct) (b) Find the speed of each ball after the collision. cue ball m/s target ball m/s
A steel ball of mass m = 1 kg and a cord of negligible mass and
length L = 2 m make up a simple pendulum that can pivot without
friction about the point O (see below). This pendulum is released
from rest in a horizontal position and when the ball is at its
lowest point it strikes a block of mass m = 1 kg sitting at rest on
a shelf. Assume that the collision is perfectly elastic and...
Two billiard balls undergo an elastic collision as shown in the figure below. Ball 1 is initially traveling along x with a speed of 15 m/s, and ball 2 is at rest. After the collision, ball 1 moves away with a speed of 7.5 m/s at an angle θ-60°. (For the following questions, assume the mass of ball 1 is equal to the mass of ball 2.) Ball Ball 1 Ball 21/<θ li (a) Find the speed of ball 2...

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3. A 2000 kg SUV traveling at 7 m/s south runs into the rear end of an 800 kg compact car sitting...
