The 860-kg motorized unit A is designed to raise and lower the 700-kg bucket B of concrete. Determine the average force R which supports unit A during the 6.2 seconds required to slow the descent of the bucket from 3.6 m/s to 1.0 m/s. Analyze the entire system as a unit without finding the tension in the cable. A B Answer: R = i kN

The roller coaster car has a mass of 700 kg, including its passenger. If it starts from the top of the hill A with a speed v A = 3 m/s, determine the minimum height h of the hill crest so that the car travels around the inside loops without leaving the track. Neglect friction, the mass of the wheels, and the size of the car. What is the normal reaction on the car when the car is at B1. find the Max g-force on passenger, bank angle2. the force required to slow down the motion and the time the force is applied must be determined to bring the coaster to rest.3. The maximum G-load experienced by a person should be no more than 5 g
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 0.6-lb particle is guided along the circular path using the slotted arm guide. Motion occurs in the horizontal plane with negligible friction. Note that the circular part of the slot has the radius equal to 0.5 ft, and the radial position, r, is measured from the hinge and the angle is measured in the counter-clockwise direction. If the arm has an angular velocity = 4 rad/sec and an angular acceleration 6 - 8 rad/sec² at the instant when 0 = 30°, determine the force of the arm guide on the particle at the instant. Present your answer in lb using 3 significant figures. 0.5 ft 0 0.5 ft.
