You are standing on a saucer-shaped sled at rest in the middle of a frictionless ice rink. Your lab partner throws you a heavy Frisbee. You take different actions in successive experimental trials. Rank the following situations in order according to your final speed, from smallest to largest (with 1 being the smallest). If your final speed is the same in two cases, give them equal rank.
(a) You catch the Frisbee and hold onto it. (b) You catch the Frisbee and throw it back to your partner.
(c) You catch the Frisbee and throw it to a third person off to the side at a right angle.
(d) You bobble the catch, just touching the Frisbee so that it continues in its original direction more slowly. (e) You catch the Frisbee and throw it so that it moves vertically upward above your head. (f) You catch the Frisbee as it comes from the south, spin around, and throw it north several times faster. (g) You catch the Frisbee and set it down at rest on the ice.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
