A 2.00 kg cart is at rest but then is released to roll down a ramp that is 1.50 m high, as in the figure below. At the bottom of the ramp the cart has a speed of 5.42 m/s. (The effects of friction can be neglected.) At the bottom of the ramp, what is the kinetic energy of the cart?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
