Help System Announcements (1 Unread) 8 days ago mment PRINTER VERSION < BACK Chapter 06, Problem 44 GO A small lead ball, attached to a 1.75-m rope, is being whirled in a circle that lies in the vertical plane. The ball is whired at a constant rate of three revolutions per second and is released on the upward part of the circular motion when it is 2.1 m above the ground. The ball travels straight upward. In the absence of...

A 1.1 kg ball is attached to a 1.35 m long string and whirled overhead in a horizontal plane. The ball goes through 3 revolutions each second. (a) The period of the ball's motion is s (b) The ball's angular speed in radians per second is rad/s (c) The ball's linear speed is m/s (d) The ball's acceleration is m/s/s (e) What force does the string exert on the ball? N

The hammer throw is a track-and-field event in which a 7.30-kg ball (the hammer) is whirled around in a circle several times and released. It then moves upward on the familiar curved path of projectile motion and eventually returns to the ground some distance away. The world record for the horizontal distance is 86.75 m, achieved in 1986 by Yuriy Sedykh. Ignore air resistance and the fact that the ball was released above the ground rather than at ground level....

A ball on the end of a string is whirled around in a horizontal circle of radius 0.340 m. The plane of the circle is 1.20 m above the ground. The string breaks and the ball lands 2.50 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion. Magnitude m/s Direction

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 small ball is attached to one end of a spring that has an unstrained length of 0.222 m. The spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 3.20 m/s. The spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0197 m. By how much would the spring stretch if it were attached to the ceiling and the ball allowed...

A small metal ball with a mass of m = 82.5 g is attached to a
string of length l = 1.30 m. It is held at an angle of ? = 56.3°
with respect to the vertical.
The ball is then released. When the rope is vertical, the ball
collides head-on and perfectly elastically with an identical ball
originally at rest. This second ball flies off with a horizontal
initial velocity from a height of h = 3.87 m,...

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...
