Answer: The distance and the direction to the water fountain are needed to describe the position of a water fountain relative to where the person is standing.

Explanation: The relative position refers to the distance from the reference point that is fixed or moving.

To find the relative position of the fixed or moving object from the observer, the distance and the direction from the object are needed.

Therefore, the second statement given in the problem is correct.

From those choices, the only one that describes the location
of the water fountain relative to you is the second one:

There are two ways to find energy. Energy=F*d=mv^2. We can use this relationship to find v:
Fd=0.5mv^{2} \\ 80*4=0.5*10v^{2} \\ 64=v^{2} \\ v=8 m/s

Kinematics practice problems Answers: 4. A race car is traveling at +76 m/s when is slows down at -9 m/s2 for 4
arlik [135]

The new velocity after 4 s is 40 m/s

The height of the spaceship above the ground after 5 seconds is 1,127.5 m

The given parameters for the first question;

  • initial velocity of the car, u = 76 m/s
  • acceleration of the car, a = - 9 m/s²
  • time of motion, t = 4 s

The new velocity after 4 s is calculated as;

v = u + at

v = 76 + (-9)(4)

v = 76 - 36

v = 40 m/s

(5)

The given parameters;

  • height above the ground, h = 500 m
  • velocity of spaceship, u = 150 m/s
  • time of motion, t = 5

The height of the spaceship above the ground after 5 seconds is calculated as;

h_y = h_0 + ut - \frac{1}{2}gt^2\\\\h_y = 500 + (150\times 5) -  (0.5\times 9.8 \times 5^2)\\\\h_y = 1,127.5 \ m
