Chapter 15, Problem 10P

The 100-kg crate is hoisted by the motor M. If the velocity of the crate increases uniformly from 1.5 m/s to 4.5 m/s in 5 s, determine the tension developed in the cable during the motion

The 145-g projectile is fired with a velocity of 580 m/s and picks up three washers, each with a mass of 96 g. Find the common velocity v of the projectile and washers. Determine also the loss |AEl of energy during the interaction. 580 m/s Answers: m/s |AE kJ

The 15-kg block is subjected to the force shown. Determine its velocity at s= 4m if v= 6 m/s at s=0. Motion occurs to the right. F= (5.1 s)N

The uniform slender rod (6.7 kg) is pinned at point O. If a 7.6-g bullet shoots into the rod with a speed of 640 m/s and becomes embedded in it, determine the total angular momentum H (in kg•m²/s) about point O immediately after that. The rod and the bullet are considered one system. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s². G 0.2 m ↓ Your Answer: 1 m Answer

If the motor draws in the cable with an acceleration of 3 m/s^2, determine the reactions at the supports A and B. The beam has a uniform mass of 30 kg/m, and the crate has a mass of 200 kg. Neglect the mass of the motor and pulleys.

The freight cars A and B have a mass of 20 Mg and 15 Mg, respectively. Determine the velocity of A after collision if the cars collide and rebound, such that B moves to the right with a speed of 2 m>s. If A and B are in contact for 0.5 s. find the average impulsive force which acts between them. 3 m/s A 1.5 m/s LUpload Choose a File

The ice-hockey puck with a mass of 0.17 kg has a velocity of 11 m/s before being struck by the hockey stick. After the impact the puck moves in the new direction shown with a velocity of 20 m/s. If the stick is in contact with the puck for 0.06 s, compute the magnitude of the average force F exerted by the stick on the puck during contact, and find the angle B made by F with the x-direction. 11 m/s 16% 20 m/s

The ice-hockey puck with a mass of 0.25 kg has a velocity of 10 m/s before being struck by the hockey stick. After the impact the puck moves in the new direction shown with a velocity of 17 m/s. If the stick is in contact with the puck for 0.06 s, compute the magnitude of the average force F exerted by the stick on the puck during contact, and find the angle ß made by F with the x-direction. 10 m/s 15% Answers: F= i B = i 17 m/s N O

The small cylinder C has a mass of 10 kg and is attached to the end of a rod whose mass may be neglected. The frame is subjected to a couple of moment M = 26Nm, and the cylinder is subjected to a force of F = (5t² + 6) N, where t is in seconds, which is always directed in the same direction as the cylinder's velocity as shown. The cylinder has a speed vo= 2 m/s when t = 0. (Figure 1) Figure 0.75 m M 1 of 1 Part A Determine the speed of the cylinder when t = 3 s.
