- Homework Statement
- A block of mass m is released from rest at the top of a ramp with a slope angle θ and height h. The friction between the block and the ramp is small and can be disregarded. After descending the ramp, the block travels a horizontal distance D (in this section the friction is not negligible) until it comes to rest. Determine, using the information given above, the coefficient of kinetic friction between the block and the horizontal plane using:
A) Newton's laws.
B) The energy equations.
- Relevant Equations
- Newton's laws equations & energy equations
Using the Newton's laws my result was h/hypotenuse and using the energy equations my result was h/D. My results are right ? And if so, how i justify the hypotenuse = D . Sorry for the bad english, the homework was poorly translated.
