To calculate the power that the motorcyclist in question should have developed, we apply the formula: N = F * V.
Values of variables: F – traction force of the motorcycle (F = 250 N); V – speed of movement (V = 72 km / h, in SI V = 20 m / s).
Let’s calculate: N = F * V = 250 * 20 = 5 * 10 ^ 3 W = 5 kW.
Answer: The motorcycle had to develop a power equal to 5 kW.
