Determine the work that produced the traction force of the car 1 kN when driving at a speed of 2 m / s in 1 min

Initial data: F (vehicle traction force) = 1 kN (1 * 10 ^ 3 N); V (vehicle speed (considered constant)) = 2 m / s; t (duration of vehicle movement) = 1 min (60 s).

We express the work done by the traction force of the car from the equality: N = F * V = A / t, whence A = F * V * t.

Let’s calculate: A = 1 * 10 ^ 3 * 2 * 60 = 120 * 10 ^ 3 J (120 kJ).

Answer: The traction force of the car produced 120 kJ of work.
