The speed of the horse remained unchanged and equal to 36 km / m during a time interval of 10 minutes, and the thrust force was equal to 1000N. What work has the horse done to move the carriage during this period of time?
To find the horse’s work done while moving the carriage, we will use the formula: A = N * t = F * V * t.
Values of variables: F – horse’s traction force (F = 1000 N); V – constant speed (V = 36 km / h = 10 m / s); t – duration of movement (t = 10 min = 600 s).
Calculation: A = F * V * t = 1000 * 10 * 600 = 6 * 10 ^ 6 J = 6 MJ.
Answer: When moving the carriage, the horse’s work in 10 minutes was 6 MJ.
