A 12 kg block is pressed against a spring with spring constant k
= 1424 N/m. The spring is
normally 65 cm long but the block is pressed against it to compress
the spring until it is only
27 cm long. The block is then released and the spring pushes it
forward onto a frictionless
surface.
a)How fast is the block moving immediately after it leaves the
spring?
b) The mass then slides across a 2.5 m wide surface with
coefficient of kinetic friction k = 0.26.
If the block crosses the friction section in 0.8 s, how much power
does it take to cross the
friction section?
c) The block then encounters another spring. It compresses that
spring 18 cm before
coming to a stop. What is the spring constant of the second
spring?

A 12-kg block is pressed against a spring (spring constant 620 N/mN/m ), compressing it some distance. The block is released from rest and slides across a track as shown in (Figure 1). While most of the track is frictionless, there is a 55-cm section of track that has a coefficient of friction with the block of 0.3. A bit further on, the track ascends into a hill that is 40-cm tall. Part A: What is the minimum compression of...
