The power of the crane motor is 3 kW. What weight can the crane lift to a height of 12 m in 1 minute?

Given:
N = 3kW = 3000W
S = 12m
t = 1 min = 60s
Find: m =?
Decision:
N = A / t
A = N * t
A = F * S = m * g * S
m = A / g * S
m = N * t / g * S = (3000 * 60) / (10 * 12) = 1500kg = 1.5t
Answer: 1500kg
