Question
Two blocks are arranged as shown. The pulley can be considered to be massless, and friction is negligible. M_1 is three times more massive than M_2. How are the magnitudes of acceleration of blocks 1 and 2 relate? Incorrect The acceleration of block 1 is greater than block 2. Incorrect The acceleration of block 1 is less than block 2. Correct: The accelerations will be equal. What is the magnitude of acceleration on block 1? If the system is released from rest, how far will Ml travel in 0.934 s?Explanation / Answer
acc of both is same
b) M2g - T = M2a ( force equation on M2)
T = M1a ( force equation on M1 )
=> a = M2g/(M1+M2) = g/4 = 2.45 m/s^2
c) S = Ut + 1/2at^2
=> S = 0 + 1/2*9.8*1/4*(0.934)^2 = 1.06 m
