Question

Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier.

Constants Part A You are a member of an alpine rescue team and must get a box of supplies, with mass 2.00 kg, up an incline of constant slope angle 30.0 ° so that it reaches a stranded skier who is a vertical distance 2.50 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00x10-2. Since you can't walk up the ncline, 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 Inm Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier.
