Dont have to answer all but with whatever you can will , you. scenario
a rock is thrown horizontally with speed v from the top of a cliff of height h,
as shown in the diagram to the right.
using representations
part a: on the diagram, choose a location for a horizontal and vertical origin. label
your choice with x = 0 and y = 0 on the diagram. choose a horizontal and
vertical positive direction and label those directions on the diagram using
arrows.
quantitative analysis
part b: identify an equation that can be used to solve for the time it takes the rock to hit the ground. write
the equation below. (if you're having trouble finding the right equation, refer to your notes, your
textbook, or the ap physics 1 equation sheet.)
part c: rearrange the equation you wrote above in part b to solve for the time it will take the rock to hit the
water. your final equation should only contain given variables and physical constants. (h, v, and
physical constants as necessary).
part d: identify an equation that can be used to solve for the horizontal distance between the bottom of the
cliff and the place where the rock lands. write the equation below.
parte: rearrange the equation you wrote above in part d to solve for the horizontal distance d between
the bottom of the cliff and the place where the rock lands. answer in terms of h, v, and physical
constants as necessary.

American eels (anguilla rostrata) are freshwater fish with long, slender bodies that we can treat as uniform cylinders 1.0 m long and 10 cm in diameter. an eel compensates for its small jaw and teeth by holding onto prey with its mouth and then rapidly spinning its body around its long axis to tear off a piece of flesh. eels have been recorded to spin at up to 14 revolutions per second when feeding in this way. although this feeding method is costly in terms of energy, it allows the eel to feed on larger prey than it otherwise could. 1.a field researcher uses the slow-motion feature on her phones camera to shoot a video of an eel spinning at its maximum rate. the camera records at 120 frames per second. through what angle does the eel rotate from one frame to the next? 2. the eel is observed to spin at 14 spins per second clockwise, and 10 seconds later it is observed to spin at 8 spins per second counterclockwise. what is the magnitude of the eels average angular acceleration during this time? 3. the eel has a certain amount of rotational kinetic energy when spinning at 14 spins per second. if it swam in a straight line instead, about how fast would the eel have to swim to have the same amount of kinetic energy as when it is spinning? 4.a new species of eel is found to have the same mass but one-quarter the length and twice the diameter of the american eel. how does its moment of inertia for spinning around its long axis compare to that of the american eel?
