In punting a football, the kicker tries to maximize both the distance of the kick and its "hang time"—the time that the ball is in the air. a kicker gets off a great punt with a hang time of 5.0 s that lands 50 yards from the kicker. what is the speed of the ball as it leaves the kicker’s foot?

Anne applies a force on a toy car and makes it move forward. what can be said about the forces acting on the toy car at the moment anne applies the force?

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.
