An 52.0 N box of clothes is pulled 7.3 m up a 30.0° ramp by a force of 103 N that points along the ramp. If the coefficient of kinetic friction between the box and the ramp is 0.22, calculate the change in the box's kinetic energy.

workin=frictionwork+changePE+changeKE

103N*7.3m=mu(mg)cos30*7.3+mg*7.3*sin30+KEchange

solve for KE change
