Physics

A box of mass ?=20.5 kg is pulled up a ramp that is inclined atan angle ?=19.0∘ angle with respect to the horizontal. Thecoefficient of kinetic friction between the box and the ramp is?k=0.305 , and the rope pulling the box is parallel to the ramp. Ifthe box accelerates up the ramp at a rate of ?=2.89 m/s2 ,calculate the tension ?T in the rope. Use ?=9.81 m/s2 for theacceleration due to gravity.
