A box with a mass of 1.80 kg slides along a flat track with friction until it makes contact with a horiztonally mounted spring. At the instant that the box makes contact with the spring the box has a velocity magnitude of 2.00 m/s. The box slides and slows down until it comes to a rest after compressing the spring 11.0 centimeters.
If the coeficient of kinetic friction between the track and box is 0.56, what is the spring constant of the spring?
| less than 400 N/m |
| greater than between 520 N/m |
| between 440 and 460 N/m |
| between 400 and 420 N/m |
| between 460 and 480 N/m |
| between 500 and 520 N/m |
| between 420 and 440 N/m |
| between 480 and 500 N/m |

A small 0.40-kg box is launched from rest by a horizontal spring
as shown in the figure below. The block slides on a track down a
hill and comes to rest at a distance d from the base of
the hill. The coefficient of kinetic friction between the box and
the track is 0.32 along the entire track. The spring has a spring
constant of 37.0 N/m and is compressed 30.0 cm with the box
attached. The block remains on...

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...
