A sled is pulled up to the top of a hill. At thetop of the hill the sled is released from rest and allowed to coastdown the hill. At the bottom of the hill the sled has a speedv and a kinetic energy E ( the energy due to the sled'smotion).1) The sled is pulled up a steeper hill ofthe same height as the hill described above. Howe will thevelocity of the sled at the bottom of the hill (after it has sliddown) compare to that of the sled at the bottom of the originalhill?
a. the speed at the bottom is greater for the steeperhill
b. the speed at the bottom is the same for both hills.
c. the speed at the bottom is greater for the orignal hillbecause the sled travels further.
d. there is not enough information given to say which speed atthe bottom is faster
e. none of the above2) Compare the kinetic energy of the sled atthe bottom for the original hill and the steeper hill in theprevious problem.
a.the kinetic energy of the sled at the bottom is greater forthe steeper hill
b. the kinetic energy of the sled at the bottom is the samefor both hills.
c. the kinetic energy at the bottom is greater for theoriginal hill
d. there is not enough info
e. none of the above are correct3) The sled is pulled up a higher hill thatis less steep than the orignal hill described at the top of thepage. How does the speed of the sled at the bottom of thehill (after it has slid down) compare to that of the sled at thebottom of the original hill?
a. the speed at the bottom is greater for the higher but lesssteep hill than for the original.
b. the speed at the bottom is the same for both hills
c. the speed at the bottom is greater for the originalhill
d. there is not enough info
e. none of the above4)For the higher hill that is less steep,how does the knietic energy of the sled at the bottom of the hillafter it has slide down compare to that of the originalhill?
a. the kinetic energy of the sled at the bottom is greater forthe higher but less steep hill
b. the kinetic energy of the sled at the bottom is the samefor both hills
c. the kinetic energy at the bottom is greater for theoriginal hill
d.there is not enough info
e. none of the above
