Abucket of water of mass 15.8 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.260 m with mass 13.0 kg . the cylinder pivots on a frictionless axle through its center. the bucket is released from rest at the top of a well and falls a distance 11.0 m to the water. you can ignore the weight of the rope. part a
what is the tension in the rope while the bucket is falling
-take the free fall acceleration to be g=9.80 m/s squared
part b
with what speed does the bucket strike the water?
-take the free fall acceleration to be g=9.80 m/s^2
part c
what is the time of fall
-take the free fall acceleration to be g=9.80m/s^2
part d
while the bucket is falling, what is the force exerted on the cylinder by the axle?
-take the free fall acceleration to be g=9.80 m/s^2
