- answer the following pleaseTwo blocks are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below. 1721 Mo i The masses of the blocks are m₁ = 16.0 kg and m₂ = 11.5 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.100 m. Block m₂ is initially on the floor, and block m₁ is initially 4.20 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the rope is small enough to be ignored, and the rope does not slip on the pulley, nor does it stretch. (a) How much time (in s) does it take block m, to hit the floor after being released? At₁ S (b) How would your answer to part (a) change if the mass of the pulley were neglected? (Enter the time, in seconds, it takes block m, to hit the floor if the mass of the pulley were neglected.)

Newton further estimated, likely based on the density of rocks, that the Earth was a solid sphere with a density about 6 times the density of water, which has density of pwater = 1 g/cm³.
