Friction Coefficient Homework: Find Speed of Block

Click For Summary
SUMMARY

The discussion focuses on a physics homework problem involving a 25.0 kg block released from a height of 3.00 meters on a frictionless ramp, transitioning to a frictional section between points B and C. The key tasks are to calculate the coefficient of friction on the rough patch and the speed of the block at point C. The user expresses difficulty in determining the coefficient of friction, which is essential for solving the speed calculation. The problem highlights the importance of understanding the relationship between gravitational potential energy, kinetic energy, and friction in mechanics.

Homework Statement


A 25.0 kg block is released from point A (on a ramp, think of a skateboarders half pipe) at 3.00 meters. The track is frictionless except from points B to C (which has a length of 6m). The block travels down the track from point A to B, at which point it hits the friction section and travels to C.

Question 1: Determine the coefficient of friction between the block and the rough patch between B and C
Question 2: Determine the speed of the block at point C

My attempts:
I'm really struggling determining the coefficient of friction. When that is determined I don't think I'll have any issues finding the speed of the block.
