You are a member of an alpine rescue team and must get a box of supplies, with mass 2.60 , up an incline of constant slope angle 30.0 so that it reaches a stranded skier who is a vertical distance 2.90 above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can’t walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 .
