Kinematics / Forces Friction Problem?

AI Thread Summary
A baseball player slides into third base at an initial speed of 7.00 m/s, with a coefficient of kinetic friction of 0.37. The problem initially appears to lack sufficient information, particularly regarding the player's mass or weight. However, it is suggested to treat the mass as a variable 'm' to proceed with calculations. This approach allows for the determination of how far the player slides before coming to rest. Ultimately, the user successfully solves the problem using this method.

Homework Statement


A baseball player slides into third base with an initial speed of 7.00 m/s. If the coefficient of kinetic friction between the player and the ground is 0.37, how far does the player slide before coming to rest?

The Attempt at a Solution


I'm not really sure how to start this problem; there doesn't seem to be enough information given. If the coefficient of friction is given, I feel like I should know what the Normal Force is, but I don't have the mass or the weight of the player, so I'm kind of lost as to how I should start this.

Help?

Call the mass 'm' and continue. Maybe you won't need the actual value. :wink:
 
Okay, thanks! That helped a bunch! I got the answer!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
