Question 3
block a is placed on a rough surface inclined at an angle θ above the horizontal. a taut string connects block a over a pulley to block b, which hangs from the string, as shown below. the masses of blocks a and b are ma and mb, respectively. at time t=0, block a is sliding up the slope as block b falls, and the blocks are both slowing down. assume that the mass and friction of the pulley are negligible.
if the mass of block b is 2kg, the gravitational force exerted on block b is most nearly which of the following?
