Asked by bob
how much force does someone have to use to hang on to a spinning merry go round if it triples its speed (while everything else remains constant)?
a) three times as much as before
b)one-ninth as much as before
c)nine times as much as before
d) one-third as much as before
e) not enough information to determine
i originally thought it'd be a, but net force is proportional to the change in velocity, so I'm not sure which answer it'd be.
