[SOLVED] Need help with pulley problem
Hi, i need help with the following question:
The sprocket assembly for a
0.800 m diameter bike wheel is
shown here. If the rider can
pedal at 50.0 rotations per
minute, what speed will the bike
be traveling? Express your
answer in km/hr. The radius of
the back sprocket is 0.050 m
and the radius of the front
sprocket is 0.150 m.
Here is the picture for reference:
