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

Can someone please help me?

Aneli [31]

Answer:

Step-by-step explanation:

to find the inverse, there are two steps

1-interchange x and y

2-solve for y

so y=x+1/x

interchange to get x=y+1/y

and solving for y we multiply both sides by y to get xy=y+1

subtract both sides by y yielding xy-y=1

factor out y to get y(x-1)=1

then divide to get y=1/x-1

Answer:

38.68 degrees

Step-by-step explanation:

In this equation you are trying to find the degrees using the hypotenuse and opposite. So you have to use the function sin^-1(5/8). Because when using Sin it is opposote ove hypotenuse.

Use binomial expansion to solve each exercise. (a) Find the coefficient of xy19 in (3x − 2y) 20.(b) Give a formula for the coeff

pishuonlain [190]

Answer:

(a) -29,884,416

(b) C(n,(n -k)/2) . . . where C(n,k) = n!/(k!(n-k)!) and k ∈ ℕ

Step-by-step explanation:

(a) The coefficient of the k-th term of the expansion is ...

C(20,k)(3x)^(20-k)(-2y)^k

For k=19, this is ...

19(3x)(-2y)^19 = -29,884,416xy^19

The coefficient of the term is -29,884,416.

(b) The p-th term of the expansion of (x +1/x)^n is ...

C(n,p)(x^(n-p)(1/x)^p = C(n,p)(x^(n-2p))

For some exponent k of x, the value of p will be ...

k = n -2p

p = (n -k)/2

Then the coefficient of x^k will be C(n, (n-k)/2), where C(n, x) = n!/(x!(n-x)!).

You will notice that there will only be a term x^k for k having the same parity as n.
