Moved from a technical forum, so homework template missing
Starting from rest, 1-kg block slides down a frictionless curved ramp, which is one quadrant of a circle, and gains 60 J of kinetic energy at the end of the curved path. The block then slides on a 6-m long rough horizontal surface and acquires a speed of 9 m/s just before going up a rough plane inclined at an angle 10 degrees with the horizontal. It continues moving with a constant speed of 6 m/s on a smooth horizontal surface where it hits and compresses a horizontal spring (k= 300 N/m) before coming to rest.
Questions:
a.) Height of the Curved ramp
b.) Speed of the block at the end of the curved path
c.) Coefficient of Kinetic Friction between the block and the rough horizontal surface
d.) Length of the inclined plane when the coefficient of kinetic friction between the block and inclined plane was 0.25
e.) Maximum compression of the string
Tried my best answering, and these are my answers:
a.) 6.1224 m
b.) 10.9545 m/s
c.) 0.3316
d.) 3.0768 m
e.) NONE as of now
Can anyone help? I'm not quite sure of my answers, Thanks.
