You are a member of an alpine rescue team and
must get a box of supplies, with mass 3.00 kg, up
an incline of constant slope angle 30.0 " so that it
reaches a stranded skier who is a vertical distance
3.20 m above the bottom of the incline. there is
some friction present, the kinetic coefficient of
friction is 6.00x10-. 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
m/s. use the work energy theorm to calculate the minimum speed v that you must give the box.

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
