24) How much work is performed by friction in slowing a 10kg object from 4 m/s to 2 m/s? 25) To avoid an accident, you slam on your brakes, skidding for a distance of 40 m before you stop. (Your anti-lock brakes were malfunctioning!). Assuming a coefficient of kinetic friction of 0.8 between your tires and the road, how fast were you going before slamming on the brakes? 26) A 1-kg block is held below a vertically mounted spring -...

After a space station is constructed, it is spun up from rest,
using rockets attached tangentially to the outside hull, in order
to simulate earth gravity for the occupants inside, shown in the
figure. We can model the station as a hoop that rotates around its
axis, and ignore the rest of the structure for the moment of
inertia.
The mass of the station is m = 50,000 kg, the outer
radius is r = 100 m.
