A car needs to generate 75.0 hp in order to maintain a constant velocity of 27.3 m/s on a flat road. What is the magnitude of the total resistive force acting on the car (due to friction, air resistance, etc.)

2048.63 N

Explanation:

Force: The product of mass and the  acceleration of a body. The S.I unit of Force is Newton(N).

From the question

P = F×V Equation 1

Where P = power generated by the car, F = Total resistive force acting on the car, V = Velocity of the car.

make F the subject of the equation

F = P/V Equation 2

Given: P = 75.0 hp = (75×745.7) = 55927.5 W, V = 27.3 m/s

Substitute into equation 2

F = 55927.5/27.3

F = 2048.63 N

Hence the total resistive force acting on the car = 2048.63 N

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
