Physics problem help please?
A box slides down a 40.6 degrees ramp with an
acceleration of 1.49 m/s2.
The acceleration of gravity is 9.8 m/s2 .
Determine the coefficient of kinetic friction
between the box and the ramp.

Comments
The acceleration a is given as 1.49 m/s^2
m is mass
μ is coefficient of kinetic friction
From free body diagram, we get equation ---->
mg sin 40.6 - μmg cos 40.6 = ma
=> g sin 40.6 - μg cos 40.6 = a
You know all the values except for μ
Use this and solve for μ
Don't worry my fellow...Talk too god and he will answer your question
Goodbye and god bless.
