A spring-loaded gun fires a 0.090-kg puck along a tabletop. The puck slides up a curved ramp and flies straight up into the air.   (a) If the spring is displaced 23.5 cm from equilibrium and the spring constant is 875 N/m, how high does the puck rise, neglecting friction? _____m   (b) If instead it only rises to a height of 5.00 m because of friction, what is the change in mechanical energy? _____ J

A certain spring has a length of 47.6 cm when a 4.49 kg mass is hung from it and a length of 58.6 cm when a 8.23 kg mass is hung from it. What is the spring constant for this spring in N/m?

A block with a mass m is initially compressing a spring by x1 on a horizontal floor with no friction. The spring has a spring constant k. The block is realeased from rest and travels a total distance of D including x1 and has a speed of v. what is the coefficent of kinetic friction between the floor and block?

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 4.80 x 10° N/m, the helper spring constant is 3.80 x 10° N/m, and Y. = 0.500 m. Truck body -"Helper" spring Main leaf spring Axle (a) What is the compression of the leaf spring for a load of 5.10 x 10° N? 0 81 (b) How much work is done in compressing the springs? 1 34 Your response differs significantly from the correct answer.

A 2.05 kg rock is dropped onto a spring from a height of 0.411 m. If the spring constant is 1951 N/m, what is the maximum compression of the spring?

You have a spring of spring constant k, and a block of mass 0.200 kg. You set the spring up vertically and compress the spring 0.300 m. It launches the block up to a max height of 2.20 m. What is the spring constant?

quick shove and moves down the incline with an initial speed v = 0.750 m/s. The incline angle is 0 = 20.0°, the spring constant is k = 465 N/m, and we can assume the surface is frictionless. By what distance (in m) is the spring compressed when the block momentarily comes to rest? A spring is attached to an inclined plane as shown in the figure. A block of mass m = 2.59 kg is placed on the incline at a distance d = 0.282 m along the incline from the end of the spring. The block is given a ww- ing. The block

A block of mass m = 3.80 kg is dropped from height h = 73.0 cm onto a spring of spring constant k = 538 N/m (see the figure). Find the maximum distance the spring is compressed.

When a 3 kg mass is hung on a vertical spring, it extends the spring by 2.00 m. What is the spring constant of the spring in N/m? (Assume g = 10m/s2).

The cable of a 1170 kg elevator cab shown in the figure below snaps when the cab is at rest at a height ?=22.9m above a spring with spring constant ?=9.08×10^4N/m. Additionally a constant friction force created by the clamps sliding along the guide rails is experienced by the cab as it moves in the shaft with strength ?f=8.14×10^3N. (a) What isthe maximum distance xthe spring compresses? (b) What is the maximum acceleration experienced by the elevator during its movement described in the problem? Assume no static friction acting on the cab since we can imagine the clamps not engaging until the moment after the cab begins to fall. Also, note that the clamps stay engaged the whole time, including while the spring is being compressed and while the elevator is bouncing back up.
