A mass M is released from rest on an incline that makes a 42° angle with the horizontal. In 3s, the mass
is observed to have gone a distance of 3m. What is the coefficient of kinetic friction between the mass
and the surface of the incline?
a. 0.8
b. 0.7
c. 0.6
d. 0.5
e. 0.3
Please help me
It would help if you could even just tell me what equation to use and please include all work
Thank you.
@Jewels Vern,
Not wanting to do someone's homework for them is one thing but don't give them the wrong answer.
@engineer,
At my age it's quite a thrill to find any answer at all for a math question.
