A boy uses a simple pulley to pull a block up a ramp. The height of the ramp is 4 m and the length of the ramp is 10 m
Assuming that the ramp is frictionless, what is the ideal mechanical advantage of the ramp and does the pulley provide any additional advantage?
А The mechanical advantage of the ramp is 2.5, and the pulley does not provide any additional mechanical advantage.
B The mechanical advantage of the ramp is 10, and the pulley does not provide any additional mechanical advantage.
C The mechanical advantage of the ramp is 40, and the pulley does provide an additional mechanical advantage.
D The ideal mechanical advantage of the ramp is 0.4, and the pulley makes it easier to pull the block up the ramp.
