You are designing a 108 cm3 right circular cylindrical can whose manufacture will take waste into account. there is no waste in cutting the aluminum for the side, but the top and bottom of radius r will be cut from squares that measure 4r units on a side. the total amount of aluminum used up by the can will therefore be upper a equals 32 r squared plus 2 pi rh, where h is the height of the right circular cylindrical can. what is the ratio of h to r for the most economical can?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
