A spring having original length of L1 is constricted by the 4 cords having length of L2. So, those cords keep spring compressed when there is nothing on the platform. Box having mass of m is placed on the platform, at the same time pushing platform further down by L3 meters. Afterwards, the platform is released from rest. Determine the height h the box rises in the air. Stiffness of spring is K=150 N/m. neglect the mass of the platform and the cords.
URGENT Collar A slides over the smooth vertical bar shown in the figure. The masses Wa = 10lbs and WB = 5lbs. When h = 0.12192m, the spring is unextended. When the system is in equilibrium, h = 0m. Determine the constant k of the spring. Note: The normal of the collar is 100 times its mass (that of the collar), remember that g = 32.16 ft/s2.
When the 3-kg box reaches point A it has a speed vA = 11 m/sm/s . Neglect friction and the size of the box. (Figure 1)
The lower block of mass m2 = 3.2 kg is pulled on by a rope with a tension force of 28 N. The upper block has mass m1 = 1.8 kg. The coefficient of kinetic friction between the lower block and the surface is 0.32. The coefficient of kinetic friction between the lower block and the upper block is also 0.32. What is the acceleration of the 3.2 kg block?
The three masses in the figure are different. The planes do not have friction with the masses and the plane of mass 3 corresponds to a quarter of a circumference. All three masses are released at the same time. The masses m2 and m3 travel the same distance. The first mass that will reach the bottom of the ramp will be: m1 m2 m3 m2 and m3 m1 and m2 m1 and m3 they will all arrive at the same time

The man is pedaling his bicycle at a constant speed up a slippery slope of 5%. The man and the bicycle have a total mass of 82 kg centered at G. If the rear wheel is about to slip, find the coefficient of friction u between the tire and the road. If the coefficient of friction were doubled, what friction force would act on the rear wheel? (Why can we neglect the friction under the front wheel?)
The roller-coaster car depicted in Figure Q3 has an empty mass of 700 kg. Additionally, the passenger inside has a mass of 75 kg. The car is released from rest at the top of the hill at A. Friction, mass of the wheels and the size of the car can be neglected. (a) Determine the minimum height of the hill crest (h) so that the car travels around inside of the loop without leaving the track. (b) Determine the maximum constant braking force which may be applied at B so that the car stops on the ground immediately after exiting the loop. (c) If the car is released from a different hill crest, with height 2.5h, how much is the car speed just before entering the loop?
The figure shows a junction of mass m = 10kg sliding on a rod in a vertical plane. Positioned 1 simpai is stationary and horizontal spring and tensioned Fp = 300N. If the spring constant is k = 1kN/m and the average frictional force between the rod and the junction is F = 30N. Calculate the speed at position 2. (Ans: 3.47m/s)

A wagon weighing 500 kN starts from rest, runs 30 meter down one percent grade and strikes the bumper post. If the rolling resistance of the track is 5 N/kN, find the velocity of the wagon when it strikes the post.
