Let M1 = 2kg. M2 = 1 kg.
W1 = F1*d1 = (M1g)*(25-5) = (2*9.8)*20 =
W2 = (1*9.8)*(24-14) =
W1/W2 =
Mass M1 has twice the mass of M2. M1 and M2 are raised from a height of 5 m to 25 m, and from 14 m to 24 m, respectively. What is the ratio of work done on mass M1 to that done on mass M2?
A. 1 : 4
B. 25 : 12
C. 4 : 1
D. 2 : 1
E. 5 : 1
