2. Calculate the KE for each car in the picture. Each car has a mass of 750 Kg. The 50 mph car, red, has a velocity of 22.35 m/sec. The 100 mph car, yellow, has a velocity of 44.70 m/sec. KE = 0.5m*V? Remember: m means mass, V means velocity. Show your calculations: Use units with numbers!

2) a cubical block of stone is lowered at a steady rate into the ocean by a crane, always keeping the top and bottom faces horizontal. which one of the following graphs best describes the buoyant force b on this block as a function of time t if the block just enters the water at time t = 0 s?
