The ball B has a mass 5 kg and is attached to the end of a 1.7 m long rod whose mass may be negligible. If the shaft is subjected to a torque of M = 3t2 + 2 N.m, where t is in seconds, determine the speed of the ball when t = 3 s. Given, the ball has a speed of 4.8 m/s when t = 0. Present your answers in m/s.
Principle of Angular Impulse and Momentum 2 of 8 To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speerd As shown, ball B, having a mass of 10.0 kg, is attached to the end of a rod whose mass can be neglected Part A - Finding the final speed of the ball If the rod is 0.550 m long and subjected to a torque M = (2.45t2 + 3.45)...
The figure shows a ball with mass m = 0.237 kg attached to the end of a thin rod with length L = 0.607 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically upward position, with zero speed...
(Undamped system) An iron ball of mass 10kg is attached to a spring having a spring constant of 3.6N/m. The ball is started in motion from rest (i.e., initial velocity is zero) by stretching the spring 0.7m from the equilibrium position with an exerted force f(t)=6.8e-t Assume there is no air resistance. a) Find the position of the ball as a function of time. b) Determine how far from the equilibrium position the ball will be after 15 seconds.
The ball A of mass 8 kg is attached to the light rod of length / = 0.77 m. The mass of the carriage alone is 204 kg, and it moves with an acceleration ao as shown. If = 2.5 rad/s when ? = 90°, find the kinetic energy T of the system if the carriage has a velocity of 1.59 m/s (a) in the direction of ao and (b) in the direction opposite to ao. Treat the ball as...
