A box with a square base and open top must have a volume of 2048 c m 3 . We wish to find the dimensions of the box that minimize the amount of material used. The length of the base is x and the height is h. Since the base is a square, the surface area of just the base would be: Area = The surface area of just one side would be: Area = The surface area of all...

You are a member of an alpine rescue team and must get a box of
supplies, with mass 2.10 kg , up an incline of constant slope angle
30.0 ∘ so that it reaches a stranded skier who is a vertical
distance 2.80 m 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...
