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 according to your final speed from largest to 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 bobble the catch, just touching the Frisbee so that it continues in its original direction more slowly. (d) You catch the Frisbee and throw it so that it moves vertically upward above your head. (e) You catch the Frisbee and set it down so that it remains at rest on the ice.

When some cars are advertised, they quote a "stopping distance" from some speed to zero.
The mass of the car and this value of "some speed" give a measure of initial motion, but we aren't necessarily told the mass.
Using the stopping distance, one can directly calculate what physical quantity provided by the brakes?
A
impulse
B
chemical potential energy
C
power
D
kinetic energy
E
force
F
velocity
G
work
H
acceleration
I
mass
The boy in the figure here is initially seated on the top of a hemispherical ice mound of radius R = 13.7 m. He begins to slide down the
ice, with a negligible initial speed. Approximate the ice as being frictionless. At what height does the boy lose contact with the ice?
