Chapter 07, Problem 38 GO A ball is attached to one end of a wire, the other end being fastened to the ceiling. The wire is held horizontal, and the ball is released from rest (see the drawing). It swings downward and strikes a block initially at rest on a horizontal frictionless surface. Air resistance is negligible, and the collision is elastic. The masses of the ball and block are, respectively, 1.7 kg and 2.5 kg, and the length of...

A steel ball of mass 0.600 kg is fastened to a cord that is 60.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 3.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. (a) Find the speed of the ball just after collision. ( in m/s) (b) Find the speed of the block just after...

A pendulum, consisting of a ball of mass m on a light
string of length 1.00 m, is swung back to a 45° angle and released
from rest. The ball swings down and, at its lowest point, collides
with a block of mass 2mthat is on a frictionless
horizontal surface.
Note that you will most likely get different numbers for the
different parts below. As usual, a good way to handle that is to
solve the problem using variables, and...

1- A ball with mass M, moving horizontally at 2.8 m/s, collides elastically with a block with mass 3.6M that is initially hanging at rest from the ceiling on the end of a 58-cm wire. Find the maximum angle through which the block swings after it is hit, in degrees. 2- A 0.15 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.72 m/s. It has a head-on collision with a 0.30...
