A crate with mass m is placed above a ramp with an angle 0, and a distance L from a spring with a spring constant k. Suppose that the ramp and crate experience a coefficient of kinetic friction µ, solve for the following: a. speed of crate before it compresses the spring b. maximum compression of the spring С. How far does the crate get to its initial distance when it rebounds? www

You are asked to design spring bumpers for the walls of a parking garage. A freely rolling 1300 kgkg car moving at 0.67 m/sm/s is to compress the spring no more than 0.066 mm before stopping.     Part A What should be the force constant of the spring? Assume that the spring has negligible mass. Express your answer in newtons per meter.

11. A 1.30-kg block is pushed against a vertical wall by means of a spring (k = 850 N/m). The coefficient of static friction between the block and the wall is 0.52. What is the minimum compression in the spring to prevent the block from slipping down? cm - ww

K L water M A 5.10 kg mass attached to a spring is travelling at a speed v; at point K, as shown above. While it is falling it is also being pushed by a spring (k = 475.00 N/m) compressed by 1.60 m (at point K). The mass travels 1.60 m (between K and L) then hits a pool of water at point L where the water exerts an average force of 54.80 N [upwards]. At point L the spring is no longer pushing and begins to stretch (in other words, at point L, x=0). The mass eventually stops at point M. If the distance between L and M is 7.45 m, determine the initial velocity of the mass (v;). Enter an answer with three digits and in S.I. units.

A cart with mass m is held at rest against a spring with spring constant k. It is compressed a distance x. When released from rest, it is launched through a frictionless track. It contains a vertical loop 7. with a radius of R. Find the force the track exerts on the cart when the cart goes through the top of the loop in terms of m, k, F, and R and any other constants.

3. A block with mass m is connected to two springs having constant forces k₁-2k and k=k. The system is initially in equilibrium on a horizontal, frictionless surface. Then, the block is pushed d distance to the right from rest, a. Draw the free body-diagram for the system and calculate the work done by the acting all forces. b. After the block release what will be the maximum speed of the block and what will be the maximum compression of spring 1? k₁ Spring 1 Spring 2

A 31.0 cm long spring is hung vertically from a ceiling and stretches to 36.9 cm when an 8.00 kg mass is hung from its free end. a. Find the spring constant (in N/m). b. Find the length of the spring (in cm) if the 8.00 kg weight is replaced with a 185 N weight.

1. Consider the setup shown below: a block with mass m; sits on a table with friction coefficient u between the table and itself, attached on one side to a spring with stiffness k, and on the other side to a cord with negligible mass that wraps over a frictionless pully and supports a second block with mass m2 that's suspended in the air over the edge of the table. The friction between block 1 and the table is not enough to hold up block 2 so that, when it's released from rest, the spring stretches a distance Ax before the system comes to rest. a. Draw and label a free-body diagram for each block. (Use the gridlines to make sure that the relative lengths of your vector arrows are correct.) k m1 block 1: block 2: m2 b. What is the kinetic friction coefficient between block 1 and the table?
