Starting from rest, a basketball rolls from the top to the bottom of a hill, reaching a translational speed of 7.7 m/s. Ignore frictional losses. (a) What is the height of the hill? (b) Released from rest at the same height, a can of frozen juice rolls to the bottom of the same hill. What is the translational speed of the frozen juice can when it reaches the bottom?

A uniform marble rolls down a symmetric bowl, starting from rest
at the top of the left side. The top of each side is a distance h
above the bottom of the bowl. (a) How far up the right side of the
bowl will the marble go if the interior surface of the bowl is
rough so that the marble rolls without slipping? (b) How high would
the marble go if the bowl's surface were frictionless? (c) For
which case...

A ball rolls down a hill from rest and collides with a block on
wheels at the bottom. The block has a mass which is 4 times larger
than the mass of the ball. Calculate the direction and velocity of
the block and ball after the collision, if they were (a) elastic,
or (b) perfectly inelastic. Please show the answers in terms of g
and h.
(c) how much of the kinetic energy is lost in the elastic
collision of...

A 12,000 N car starts from rest and rolls down a hill from a
height of 10.0 m (see figure). It then moves across a level surface
and collides with a light spring-loaded guardrail.
(a) Neglecting any losses due to friction, and ignoring the
rotational kinetic energy of the wheels, find the maximum distance
the spring is compressed. Assume a spring constant of
1.2 106 N/m.
? m
(b) Calculate the maximum acceleration of the car after contact
with the spring,...

A ski jumper starts from rest from point A at the top of a hill
that is a height h1 above point B at the bottom of the hill. The
skier and skis have a combined mass of 80 kg. The skier slides down
the hill and then up a ramp and is launched into the air at point C
that is a height of 10m above the ground. The skier reaches point C
traveling at 42m/s.
(a) Is the...

A skier starts from rest at the top of a hill that is inclined
at 10.8° with respect to the horizontal. The hillside is 245 m
long, and the coefficient of friction between snow and skis is
0.0750. At the bottom of the hill, the snow is level and the
coefficient of friction is unchanged. How far does the skier glide
along the horizontal portion of the snow before coming to rest?

A skier starts from rest at the top of a hill that is inclined
at 10.9°
with respect to the horizontal. The hillside is 190
m long, and the coefficient of friction between snow and skis is
0.0750. At the bottom of the hill, the snow is level and the
coefficient of friction is unchanged. How far does the skier glide
along the horizontal portion of the snow before coming to
rest?

Explain how to use derivatives to find the top of a hill or the
bottom of a valley on a graph?
What does it even mean for a derivative to not exist and why is
this involved? And what does that have to do with a derivative of
zero?
