Answer:  B

<u>Explanation:</u>

E shows the direction of the ball but the question asks about the direction of the STICK, which is the opposite of the ball.

Explanation:

The ball's horizontal velocity changes from vi to 0, so the acceleration is negative, meaning the force component must point to the left.

The ball's vertical velocity changes from 0 to vf, so the acceleration is positive, meaning the force component must point up.

So you're looking for a force that points to the left and up, where the horizontal component is greater than the vertical component.

<span>To answer this question with specific values, you would need a phase diagram for the substance in question. In more general terms, the pressure needs to be lower than the pressure of the triple point, the substance must be present in its solid state, and the temperature must rise high enough to produce a gas.</span>

Find the magnitude of the vector v given its initial and terminal points. Round your answer to four decimal places.
Sliva [168]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is |v| = 6.93

Explanation:

From the question we are told that

    The initial point is (x_1 , y_1 , z_1 ) = (-1 , 7 , 4 )

    The  terminal point is  (x_2 , y_2 , z_2) = (-5 , 11, 8 )

Generally the magnitude of the vector is mathematically represented as

     |v| = \sqrt{(x_2 -x_1 )^2 + (y_2 - y_1 )^2 + (z_2 -z_1)^2}

=>   |v| = \sqrt{(-5 -(-1) )^2 + (11 - 7 )^2 + (8 -4)^2}

=>   |v| = 6.93
