Two blocks of ice, one four times as heavy as theother, are at rest on a frozen lake. a person pushes each block thesame distance d. ignore friction and assume that an equal force f_vec is exerted on each block.
this is what i have sofar:
parta
which of the following statements istrue about the kinetic energy of the heavier block after thepush?
it is equalto the kinetic energy of the lighter block.
partb
compared to the speed of the heavierblock, how fast does the light block travel?
twice asfast
this is what i cant figure out:
partc
now assume that both blocks have thesame speed after being pushed with the same force f_vec. what can be said about the distances the two blocks arepushed?
a the heavyblock must be pushed 16 times farther than the lightblock.
b the heavyblock must be pushed 4 times farther than the lightblock.
c the heavyblock must be pushed 2 times farther than the lightblock.
d the heavytblock must be pushed the same distance as the lightblock.
e the heavyblock must be pushed half as far as the light block.
