Two people are competing in a tubing competition. They push a 132 kg inner tube. If the combined push of the team is 450 N and the inner tube also
experiences a friction force of 35 N, what is the acceleration of the inner tube? (F
=ma)

Explanation:

Given that,

Mass of the tube, m = 132 kg

Force = 450 N

Friction force, f = 35 N

Net force,

F = 450 - 35

F = 415 N

Let a be the acceleration. We know that,

F = ma

So, the acceleration is .

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
