SUMMARY

The discussion centers on a physics problem involving a block sliding up a frictionless track and then stopping due to friction on a higher level. The initial speed (v0) is 6.0 m/s, the height difference (h) is 1.2 m, and the coefficient of kinetic friction (µk) is 0.60. The participant initially struggles to determine the stopping distance (d) due to the absence of the block's mass, which is necessary for calculating the normal force and frictional force. Ultimately, the participant realizes that they overlooked a variable necessary for solving the problem.

Homework Statement



In Figure 8-50 (nothing important other than 1.2 m height difference, the higher level is completey flat), 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 v0 is 6.0 m/s, the height difference h is 1.2 m, and the µk is 0.60. Find d.

Vo = 6.0 m/s
h = 1.2 m
µk = 0.60
m = ? (not given)

Homework Equations



Conservation of energy to get initial velocity upon reaching the higher level (this is already done and verified)

Then for the friction force we need the normal force (in this case weight of block), which is not given...

The Attempt at a Solution



So I already have the initial velocity at the higher level done and verified that part is correct, but I don't think the distance d it takes to come to a stop can be found since they never gave the weight of the block (so unknown magnitude of friction force).

Am I missing something here?
