Homework Answers
The velocity with which the block slides is independent of the mass of the block. Thus, both the blocks slide down at constant speed even though the second mass is 4 times greater than that of the first.

2. Starting from rest, a block of mass m slides down a frictionless incline at angle θ(0◦ < θ < 90◦) where it runs into a spring of spring constant k. When the block momentarily stops, it has compressed the spring by distance x. Find expressions for (a) the distance the block slides down the incline from when it is released to when it momentarily stops (b) the distance between the point of the first block-spring contact and the point...

An initially stationary block of mass 0.5kg is on an incline angled 20° above the horizontal. When released, it slides down the frictionless incline undergoing a vertical displacement of 4m and then travels across a rough horizontal surface to a spring constant 600 N/m. The block compresses the spring 20 cm from its equilibrium position before momentarily coming to a stop. D.) Naturally after momentarily stopping on the incline, the block will slide back down. Does it make it to...

A block of mass m = 2.26 kg slides down an α = 32.8 ° incline
which is h = 3.54 m high. At the bottom, it strikes a block of mass
M = 7.22 kg which is at rest on a horizontal surface, as seen in
figure below. (Assume a smooth transition at the bottom of the
incline.) If the collision is elastic, and friction can be ignored,
determine the speed of the smaller block after the collision.
