You are pushing a sled in which your little sister is seated up a 21° slope (one that makes an angle of 21° with the horizontal). if the mass of the sled and girl is 47 kg, and the coefficient of kinetic friction between the sled and the surface is 0.100, with what magnitude of force do you need to push in order for the sled to move with constant velocity?

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
