Question

A 2.00 kg hoop with a radius of 0.0750 m was placed at the top of a3.00 m long ramp. The top of the ramp was 0.800 m above the lowerend of the ramp. The hoop rolled down the ramp.
a) Calculate the hoop’s total mechanical energy at the top of theramp.
b) What is the hoop’s total mechanical energy at the bottom of theramp?
c) Calculate the hoop’s speed at the bottom of the ramp.
d) Calculate the hoop’s angular velocity at the bottom of theramp.
e) Calculate the hoop’s acceleration (linear acceleration).
f) Calculate the hoop’s angular acceleration.
g) Calculate the time required for the hoop to roll down theramp.
h) Calculate the hoop’s kinetic energy (linear kinetic energy) atthe bottom of the ramp.
i) Calculate the hoop’s rotational kinetic energy at the bottom ofthe ramp.
