Simple Problem, I think theres not enough information

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?

oh nvm i randomly dropped a variable -____-

I agree with your assessment that there is not enough information provided in the problem to solve for the distance d. The weight of the block is a crucial piece of information needed to calculate the normal force and ultimately the frictional force that stops the block. Without this information, it is impossible to accurately determine the distance d. I suggest reaching out to the instructor or providing a range of possible values for the weight of the block in order to solve for d.
