A bowling ball weighing 71.2 NN is attached to the ceiling by a
3.50 mm rope. The ball is pulled to one side and released; it then
swings back and forth like a pendulum. As the rope swings through
its lowest point, the speed of the bowling ball is measured at 4.40
m/s.
Part A
At that instant, find the magnitude of the acceleration of the
bowling ball.
Part B At that instant, find the direction of the acceleration of...

A bowling ball weighing 71.2 N (=mg) is attached to the ceiling by a 3.40 m rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. The ball is initially pulled back so it is a vertical height of 2.2 m above the lowest point of the ball's swing. 1. When the ball is at its lowest point in its swing, what is the acceleration of the bowling ball, in magnitude...

The act of bowling a ball can be rather involved, but in its simplest form the bowler swings her arm in a roughly circular arc, releasing the ball just amoment after it passes through the bottom of the arc. By the time the ball is at the bottom of the arc, its speed is not changing anymore. A decent bowler can make the ball travel the length of the 60-ft alley in about 2.1 s. In this problem, we'll ignore...

5. 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 inelastic. The masses of the ball and block are, respectively, 1.5 kg and 2.4 kg, and the length of the wire is 1.21...

An aluminum cable with cross-sectional area 1.50 times 10^-6 m^2 is suspended from the ceiling. A mass is suspended from the free end of the cable to keep the cable straight and at a certain length. If the temperature of the cable is reduced by 10 C degree, by how much should the suspended mass be increased so that the length of the cable remains the same? The coefficient of linear expansion for aluminum is alpha = 23 times 10^-6...

A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall whle the other end is connected to a movable object. The spring and object are compressed by 0.082 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.9 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.041 m relative to its unstrained length? _______ m/s

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...
