4. A 490 g dynamics cart is held at rest next to a Hooke's Law spring that is compressed by 44.0 cm. The spring has a force constant of 150 N/m. The cart is released and travels along a horizontal surface; the surface is smooth except for a 1.0 m rough patch where a 4.0 N force of friction acts. The cart then travels along a frictionless incline. What is the maximum height (h) reached by the cart, above the horizontal surface? h 1.0m rough patch

A mass and a spring A 3.4 kg block slides 3.3 m across a frictionless, horizontal table at 2.2 m/s, moving left. Once the block hits the spring, it sticks, compressing the spring 70 cm before the block stops and reverses direction. The block then continues to bounce back and forth, still attached to the spring. The spring constant is 33.6 N/m. Ignore air resistance. 2.2 m/s 3.3 m 70 cm 1. Plot the position of the block as a function of time, with t = 0 when the block first hits the spring.

To measure the static friction coefficient between a 4.50-kg block and a vertical wallI, the setup shown in the drawing is used. A spring (spring constant = 498 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.0466 m, what is the coefficient of static friction? Number i Units
4. A 3kg block sits on a ramp, against a spring. I pull back on the block, compressing the string by 4cm, and the block moves 1.4m up the ramp, so that it is 0.5m higher than it was before, before it stops. If the force of kinetic friction on the block from the ramp is K = 7N, find the spring constant k. Ef = Ei 0.5m + 1.4m W

2. Maria and Rory are using a spring launcher to move a 125 g block to the top of a ramp. The spring launcher is at the base of the ramp and consists of a platform and a spring with a force constant of 420 N/m. The horizontal surface at the base of the ramp is smooth and frictionless. They compress the spring by 0.12 m with the block resting against the spring launcher. Once they let go, the block travels up the 1.4 m ramp and comes to rest at the top of the ramp. The top of the ramp is 1.0 m above the ground. Ramp Experiment Ad= 1.4 m smooth frictionless surface What is the average frictional force acting on the block as it moves up the ramp? Ah=1.0 m
