a wagon is pulled at speed of 40.0 m/s by a horse exerting 1800 newton horizonal force what is the power of horse

Sonbull [250]

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

$\:\:\:P=\overrightarrow{F\cdot }\overrightarrow{v}$

The ⋅ in the formula represents a scalar product, defined by:

$\overrightarrow{v\cdot }\overrightarrow{w}=|v||w|cos\:\theta$

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

Multiply: 0.063 x – 0.0096=

Ahat [919]

Answer:

-0.0006048

Explanation:

Given the expression:

$0.063\times-0.0096$

We can write the expression in the form below:

$=\frac{63}{1,000}\times-\frac{96}{10,000}$

Next, we simplify the result.

$\begin{gathered} =\frac{-63\times96}{1,000\times10,000} \\ =-\frac{6048}{10.000,000} \\ =-0.0006048 \end{gathered}$

Therefore:

$0.063\times-0.0096=-0.0006048$
