I believe the correct answer is kinetic energy.

We know that kinetic energy is the movement of any object, no matter its size.

Mechanical energy is a type of kinetic energy, which involves the movement of larger objects.

I hope I helped!

If you need a more thorough explanation, don't hesitate to message me or leave a comment down below.

Here's a video that explains energy:

An intergalactic rock star bangs his drum every 1.50 s. A person on earth measures that the time between beats is 2.70 s. How fa

sineoko [7]

Answer:

v = 83.1 % of speed of light

Explanation:

given,

T_e is the earth time = 2.7 s

T_s is the ship time = 1.5 s

we know,

$T_s = T_e \times \gamma$

where c is the speed of light

v is the speed of the rock star moving

$T_s = T_e\times \sqrt{1-\dfrac{v^2}{c^2}}$

$1.5= 2.7\times \sqrt{1-\dfrac{v^2}{c^2}}$

$\sqrt{1-\dfrac{v^2}{c^2}} =0.556$

squaring both side

$1-\dfrac{v^2}{c^2}=0.3086$

$v^2=0.6914c^2$

v = 0.831 c

v = 83.1 % of speed of light

2. A marble is rolling at a velocity of 1.5 m/s with a momentum of 3.0 kg×m/s. What is its mass?

Nikolay [14]

Answer:

m= 2[kg]

Explanation:

Linear momentum can be calculated as the product of mass by Velocity.

$P=m*v$

where:

P = linear momentum = 3 [kg*m/s]

v = velocity = 1.5 [m/s]

m = mass [kg]

$m=P/v\\m=3/1.5\\m=2[kg]$
