Answer:
The power of horse is: P = 72000 W
Step-by-step explanation:
Given
- F = 1800 N
- v = 40.0 m/s
To determine
P = ?
Using the formula
The ⋅ in the formula represents a scalar product, defined by:
The angle Ф is zero because F and v are are parallel.
Thus the cosine is 1.
Therefore,
P = (1800) (40.0)
P = 72000 W
Hence, the power of horse is: P = 72000 W
