Question

A crate slides down a 35o ramp with constant speed. What is the coefficient of kinetic friction between the crate and the ramp?


A. 0.08
B. 0.42
C. 0.7
D. 1.2

Answer 1

i can almost remember the physics equations, but they deal with forces

Answer 2

F = ma
F = un

u = ma/n

Answer 3

Constant speed = Forces are equal

Answer 4

Therefore Ff = mgsin35.
Ff = uFn = u(mgcos35)
=>
u(mgcos35) = mgsin35
u = mgsin35/(mgcos35)
u = tan35

Answer 5

Total Energy = Energy remaining + Energy lost was one idea i was having, but its been a long day lol

Answer 6

hahaha one mark for effort amistre
