Which response accurately describes a balanced force?
question 7 options:
a. a 25-n force acts on the left side of the marble at the same time as a 25-n force acts on the right side of the marble.
b. a marble resting on the sidewalk suddenly begins to roll downhill without being touched.
c. a 2-n force presses down on the marble at the same time as a 1.5 n-force presses up on the marble.
d. a marble rolling downhill suddenly comes to rest at a garden wall.

a. A 25-N force acts of the left side of the marble at the same time as a 25-N force acts on the right side of the marble.

Explanation:

When trying to balance an object, you must keep the same amount of weight on each side to keep it in the middle. Think of a seesaw: whatever side has more weight pressure is the side that falls first. Hence, the correct answer is A.

The vertical component is = vsinx m/s

If you know the angle, substitute the value of x.

If you know the velocity at which it is moving, substitute it for v
