A 1.88 kg mass is released from rest while on and incline of 57.18 degrees. If the coefficient of kinetic friction is 0.455, what is the magnitude of the acceleration of the mass

Expert Solution
Step 1

Consider the free body diagram below,

 

The frictional force on mass is,

Fr=μkN                            (I)                 μk=coefficient of kinetic friction,N=normal force=mg

Substitute the values in equation (I) to find the frictional force,

Fr=μkmg    =0.4551.88 kg9.8 m/s2    =8.38 N
