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 B find the Max g-force on passenger, bank angle the force required to slow down the motion and the time the force is applied must be determined to bring the coaster to rest. The maximum G-load experienced by a person should be no more than 5 g and fint the bank angle B h 15 m

3/80 The 2-kg collar is at rest in position A when the constant force P is applied as shown. Determine the speed of the collar as it passes position B if (a) P = 25 N and (b) P = 40 N. The curved rod lies in a vertical plane, and friction is negligible. VAnswer (a) no motion, (b) UB= 5.62 m/s 1.6 m A 0.8 m B P 35⁰ PROBLEM 3/80 35°

Q3: The 3-lb collar is released from rest at A and slides freely up the inclined rod, striking the stop at B with a velocity v. The spring of stiffness k = 1.8 lb/ft has an unstretched length of 15 in. Calculate the kinetic energy and v. Note: Use the equation of principle of work and kinetic energy in solution.

When s = 0.6 m, the spring is relaxed, and the 10 kg block, which issubjected to a force of 125 N, has a speed of 4 m/s on the smooth plane.Find the distance s when the block stops.

The motor winds in the cable with a constant acceleration, such that the 20-kg crate moves a distance s = 6 m in 3 s, starting from rest. Determine acceleration. what is the normal force (N) at point A. Determine the tension developed in the cable. The coefficient of kinetic friction between the crate and the plane is u= 0.3.

The 925-kg motorized unit A is designed to raise and lower the 615-kg bucket B of concrete. Determine the average force R which supports unit A during the 5.9 seconds required to slow the descent of the bucket from 4.6 m/s to 0.9 m/s. Analyze the entire system as a unit without finding the tension in the cable. Answer: R = i kN

The 4-lb collar is compressed against a spring a distance of 6 inches and then releasedfrom rest. The spring can be considered elastic and has a constant of k = 10 lb/in. Thespring is not adhered to the collar, and can be considered massless, so it will notextend into tension.   Plot the acceleration of the collar as a function of x for x = 0 to 7 inches.What is the velocity as the collar leaves the spring?

3/167 The baseball is traveling with a horizontal velocity of 85 mi/hr just before impact with the bat. Just after the im- pact, the velocity of the 5-oz ball is 130 mi/hr directed at 35° to the horizontal as shown. Determine the x- and y- components of the average force R exerted by the bat on the baseball during the 0.005-sec impact. Comment on the treat- ment of the weight of the baseball (a) during the impact and (b) over the first few seconds after impact. 130 mi/hr 35° 85 mi/hr

Determine the speed v which the 690-kg four-man bobsled must have in order to negotiate the turn without reliance on friction. Also find the net normal force N exerted on the bobsled by the track. 23° Answers: V= i N = i -p=58 m m/s kN
