15-2. Determine the linear momentum of the 10-kg block. 2 m/s 30°

The ball with a mass of 5 kg is attached to the rod (with negligible mass), which rotates about O in the horizontal plane. A couple moment M = 0.5 t2 N-m is applied to the system, where t is in seconds. Determine the speed of the ball at the instant t = 10 s starting from rest.

2. The 10-Ib block has a speed of 4 ft's when the force of F= (8t?) Ib is applied. Determine the velocity of the block when t= 2 s. The coefficient of kinetic friction at the surface is = 0.2. v = 4 ft/s F= (8°) lb

The pavement compactor is traveling down the incline at VG = 5 ft/s when the motor is disengaged. The body of the compactor, excluding the rollers, has a weight of 8000 lb and a center of gravity at G. Each of the two rear rollers weighs 400 lb and has a radius of gyration of KA = 3.3 ft. The front roller has a weight of 800 lb and a radius of gyration of kg = 1.8 ft. The rollers do not slip as they rotate. (Figure 1) Figure 3.8 ft 5 ft A GT 10 ft 1 of 1 30 730 ▼ Part A Determine the angular velocity of the roller B when the compactor has traveled 16 ft down the plane.

The collar with mass of 0.7 kg is released from rest at position A and travels down the smooth circular rod in the vertical plane. If the velocity of the collar at Point C is 3.3 m, determine the tangential component of acceleration of the collar (in m) at Point C. The spring has a stiffness of k = 140 N and an unstretched length of 0.5 meters. Consider R = 1.7 meters, 0 = 33°, and g =10 A m R/2 D В R

The uniform slender rod (7.1 kg) is pinned at point O. If a 5.4-g bullet shoots into the rod with a speed of 660 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. G1m 0.2 m

When 0=60°, the boy's center of mass G has a speed of 10 ft/s as he swings to the right. Determine the rate of increase in his speed and the tension in each of the two supporting cords of the swing at that instant. The boy has a weight of 60 lb. 10 í
