In the figure, a 2.6 kg block is accelerated from rest by a
compressed spring of spring constant 660 N/m. The block leaves the
spring at the spring's relaxed length and then travels over a
horizontal floor with a coefficient of kinetic friction
?k = 0.272. The frictional force stops the
block in distance D = 7.9 m. What are (a)

A 2.1.0-kg block is accelerated from rest by a compressed spring (ks = 545 N/m). The block leaves the spring at the spring’s relaxed length. The block then travels along a rough horizontal with a coefficient of kinetic friction μk = 0.240 a distance of x = 6.90 m before frictional force stops the block. What was the original compression distance of the spring?

In the figure below, a block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo; the height difference is h and the coefficient of kinetic friction is Wk. Find d in terms of the given variables (use g where applicable). u-0- In...

In the figure below, a block of mass m = 2.0 kg slides head into a spring of spring constant k = 320 N/m. When the block stops, it has compressed the spring by 6.5 cm. The coefficient of kinetic friction between the block and floor is 0.15. (a) While the block is in contact with the spring and being brought to rest, how much work is done by the spring force? (b) What is the increase in the thermal...
