Answer:
mass
Explanation:
astronomers use Newtons gravitational law as a link between gravity and orbits to measure the masses of stars and planets.
Newtons gravitational law states that the gravitational force of attraction between two planets is proportional to their masses and inversely proportional to the square of the distance between them.
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.
C. see image
Explanation:
Full disclosure not totally sure what you are being asked in the last one but I put togethere a rough sketch that is my best guess.
A. What can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>
<h3>
What is the principle of conservation of energy?</h3>
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
The energy of a system can be converted from one form to another.
Thus, what can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>

Momentum = mass (kg) * velocity (m/s)
<span>Total mass = mass of bike + mass of Rita = 7 + 42 = 49 Kg </span>
<span>Momentum = 49 * 15 = 735 = 7.35 * 10^2 = 7.4 * 10^2 to one decimal place
Final answer is </span><span>7.4 × 102 kilogram m/s</span>
