A truck and a car are set to collide. The truck is moving at a velocity of 20 m/s and has a mass of 1500 kg. The car is moving at an unknown speed and has a mass of 750 kg. How fast must the car be going to cause both the truck and car to stop when they collide? (Hint: For both the car and the truck to stop, the car and trucks momentum must be equal.)

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.

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.)
