The tractor moves the platform at a speed of 7.2 km / h, developing a pulling force of 25 kN. What work will the tractor accomplish in 10 minutes?
Data: V (platform speed) = 7.2 km / h = 2 m / s; F (tractor pulling force) = 25 kN = 25 * 10 ^ 3 N; t (running time) = 10 min = 600 s.
Work when moving the platform: A = N * t = F * V * t = 25 * 10 ^ 3 * 2 * 600 = 30 * 10 ^ 6 J.
Answer: In 10 minutes, the specified tractor will perform work of 30 MJ.
