Question 3 ) 30110 (> Part A Two blocks with different masses are attached to either end of a light rope that passes over a light If the total mass of the two blocks is 29 0 kg . what is the mass of the heavier block? pulley suspended from the ceiling. The from rest, and the more massive one starts to descend. After this block has 1.20 m, its speed is 3.00 m/s. m Value Units X Incorrect; Try Again; 4 attempts remaining If the total mass of the two blocks is 29.0 kg, what is the mass of the lighter block? Express your answer with the appropriate units. mValue Units Submit

Explanation / Answer

Applying vf^2 - vi^2 =2 a d

3^2 - 0^2 = 2(a)(1.20)

a = 3.75 m/s^2  

(A) a = (m2 - m1)g / (m1 + m2)

m1 + m2 = 29 ..... (i)

m1 - m2 = 29 x 3.75 / 9.81 = 11 .... (ii)

(i)+(ii) => m1 = 20 kg ......Ans

(B) m1 = 29 - 20 = 9 kg ....Ans
