Homework Statement
A block(7 kg) is released from rest on an inclined plane of 23 degrees and moves 2.8 m during the next 4.7 s. The acceleration of gravity is 9.8 m/s^2. What is the magnitude of the acceleration of the block? What is the coefficient of kinetic friction for the incline?
Homework Equations
The Attempt at a Solution
I already calculated the acceleration of the block which is 0.2535 m/s^2.
Fn=mgcos23=63.14663295
Fx=ma=Ff-mgsin 23
7(0.2535) = 63.14663295 * (coefficient) - 26.80415541
coefficient = 0.452576077
Can you check my calculation please?
