SUMMARY
The maximum speed of a horse can be estimated using its dimensions and the concept of drag force. Given a horse that is 1.8 m tall and 0.5 m wide, the drag force can be calculated using the formula Drag = (1/4)(0.9 m^2)v^2, resulting in Drag = 0.225v^2. By equating the power output of a horse, approximately 1 horsepower (746 W), to the drag force, the maximum speed is calculated to be 14.9 m/s.
