A 2-kg block is initially at rest and pressed against a spring (k = 500 N/m) at A compressing the spring by x m. It slides down a ramp and into a circular loop, both have negligible friction. The diameter of the circular loop is equal to 4 m. NOTE THAT A and B HAVE THE SAME ELEVATION. If the block is to move from section A to B and maintains its contact to the circular loop thoughout, answer the following questions:

Question
Transcribed Image Text:A 2-kg block is initially at rest and pressed against
a spring (k = 500 N/m) at A compressing the spring
by x m. It slides down a ramp and into a circular
loop, both have negligible friction. The diameter of
the circular loop is equal to 4 m. NOTE THAT A and
B HAVE THE SAME ELEVATION. If the block is to
move from section A to B and maintains its contact
to the circular loop thoughout, answer the
following questions:
A
B
4 m
1. What is the minimum magnitude of velocity that
the block should have at B so that it stays in
contact with the circular loop?
2. What force/s do/does NOT do any work on the
package as it moves from A to any section along
the track?
3. What is the change in the total potential energy
of the block as it moves from A to to B?
4. What is the distance x that the spring should be
compressed so that the block will maintain contact
with the circular loop at B?
