C.
Because it’s falling it has acceleration in the y direction. If you have acceleration, you usually also have velocity, and since kinetic energy is KE= Mv^2 you know you have it. It also has potential energy because it has some height to it, and PE= Mgh.

The sum of the initial and final velocity is divided by 2 to find the average.
4vir4ik [10]

The average velocity is obtained by ( u + v)/2.

<h3>What is average velocity?</h3>

The term velocity refers to the rate of change of displacement with time. Velocity is a vector quantity thus it has both magnitude and direction. The velocity of a body could also be shown by the use of the vector notation.

To obtain the average velocity;

Let the initial velocity be u

Let the final velocity be v

It then follows that the average velocity = ( u + v)/2

A sperm whale can accelerate at about 0.0800 m/s 2 0.0800 m/s 2 when swimming on the surface of the ocean. How far will a sperm
Norma-Jean [14]

Answer:

26.64 m

Explanation:

Given the following :

Acceleration at ocean surface = 0.0800 m/s²

Distance covered if initial speed = 0.700 m/s and accelerates to a speed of 2.18m/s

Using the equation :

v² = u² + 2as

Where ;

v = final velocity ; u = initial velocity ; a = acceleration ; s = distance covered

Therefore,

v² = u² + 2as

2.18² = 0.7² + (2 × 0.08 × s)

4.7524 = 0.49 + 0.16s

4.7524 - 0.49 = 0.16s

4.2624 = 0.16s

s = 4.2624 / 0.16

s = 26.64 m

Brut [27]

Answer:

V/A

Explanation:

Resistance equals voltage divided by current. You already know resistance's unit is the Ohm. Voltage's unit is the Volt and current's is ths Ampere. Now you can do something like this:

1Ω=\frac{1V}{1A} ⇔

Ω=V/A

Hope this helped :)
