A 27.4 kg dog is running northward at 2.19 m/s , while a 7.19 kg cat is running eastward at 2.78 m/s . Their 75.7 kg owner has t

cupoosta [38]

Answer:

$\| \vec v\| = 0.836\,\frac{m}{s}$ , $\alpha = 71.577^{\textdegree}$ (Northeast)

Explanation:

Let consider that owner has the resultant direction of the momentums from the dog and the cat. First, the momentum of the owner is:

$\|\vec p \| = \sqrt{\left[(27.4\,kg)\cdot \left(2.19\,\frac{m}{s} \right)\right]^{2}+\left[(7.19\,kg)\cdot \left(2.78\,\frac{m}{s} \right)\right]^{2}}$

$\|\vec p \| = 63.248\,kg\cdot \frac{m}{s}$

The speed of the owner is:

$\|\vec v \| = \frac{63.248\,kg\cdot \frac{m}{s}}{75.7\,kg}$

$\| \vec v\| = 0.836\,\frac{m}{s}$

Lastly, the direction of the owner is:

$\alpha = \tan^{-1}\left[\frac{(27.4\,kg)\cdot \left(2.19\,\frac{m}{s} \right)}{(7.19\,kg)\cdot \left(2.78\,\frac{m}{s} \right)} \right]$

$\alpha = 71.577^{\textdegree}$ (Northeast)

ANSWER ASAP . Which of the screws below requires the least amount of effort force to turn?

tigry1 [53]

Answer:

Screw X

Explanation:

In the screw x, the threads of the inclined plane are closer together. Therefore this screw has a greater mechanical advantage and hence it is easier to turn than the other screws.
Therefore,it takes less force to penetrate the wood with the screw X.

Can someone help me?!!

Fantom [35]

<h2>Hello!</h2>

The answer is:

The first option, the force tending to lift Rover is equal to 14.5 N.

To calculate the force that is tending to lift Rover vertically, we need to calculate the vertical component force.

Since we know that the angle between the force and the ground is 29°, we can calculate the vertical component of the force using the following formula:

$F_y=Force*Sin(29\°)$
