i was just looking for some confirmation on the kinetic friction part of the problem. so, anytime a problem asks for kinetic friction and i don't have the mew value, i can just subtract the net force down the ramp from the force of gravity in the x direction? i think i realized that the...
A 115.0 kg box slides down a 25.0 degree ramp with an acceleration of 2.60 m/s squared. Find the normal force, the net force down the ramp, and the force of kinetic friction.
Gravity = 9.81 m/s2
Force of gravity = ma
Mew k = Force of Kinetic Friction/Normal Force
These are the parts that I've...
