</u></em>

B. two-thirds
<span>C. one-fourth</span>
Answer:
The answer to your question is: a = 2 m/s²
Explanation:
I' ll solve it in this way, tell me if I'm right. Because we need to consider that in the moon there is no gravity.
Data
F = 50 N
a = 4.0 m/s²
Moon
F = 25 N
a = ?
Formula
F = m x a
First, calculate the mass
m = F / a
m = 50 / 4
m = 12.5 kg
Now, calculate the acceleration
a = F / m
a = 25 / 12.5
a = 2 m/s²
Answer & Explanation:
This can be explained with Newton's first law, Inertia - if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
When you walk, your entire body is in a forwarding motion. If your toe hits an object (in this case, a chair), only this unfortunate toe will stop while the rest of your body continues its forwarding motion, resulting in you falling forward.
Answer:
in the ball
Explanation:
potential energy is where an object has energy, always, but it isn't always moving, and when you drop the ball, it has kinetic energy.
