Consider the two rotating pulley-like systems above. They are identical in every way EXCEPT the mass of the pulley on the left is concentrated on the outside edge (ring or hoop shape), while the mass of pulley on the right is evenly distributed throughout the pulley (disc or cylinder shape). Given R =0.15m, M =0.6 kg, and m= 0.5 kg. Both pulley systems are initially at rest and the block masses are a height of 0. 8m above the ground. Required:
a. If both masses are released at the same time, which pulley will hit the ground first?
b. If both masses are released at the same time, which pulley will hit the ground first?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
