Andrews [41]3 years ago
7 0

Answer:

Have in mind: Energy is always conserved and, (...) be transferred between objects or systems, from one form to another.

Hence, the true relation is C, when a system gains kinetic energy, it loses potential energy.

Think about this,

K + P = constant

If K increases, then P need to decreases to holds the above relation.

What should a free-body diagram look like for a skydiver who has opened his parachute and is now slowing down as he falls?
Ksivusya [100]

Answer:

There is an arrow up for air resistance and an arrow down for gravity. The arrow up is longer than the arrow down.

Explanation:

The text of the problem says that the skydiver is slowing down: this means that he has an acceleration, which is directed opposite to the motion of the skydiver. Since the motion is downward, the acceleration must be upward.

There are two forces acting on the skydiver: the gravity (downward) and the air resistance (upward). According to Newton's second law:

F=ma

the acceleration has the same direction of the net force, so the net force must also be upward: therefore, the air resistance must be greater than the gravity, so the arrow up for air resistance is longer than the arrow down for gravity.

A rolling ball with a mass of 1.01 kg crashes into a wall. The wall exerts a force of 2.40 Newtons and stops the ball. What was
klemol [59]

Answer:

Acceleration, a = 2.38m/s²

Explanation:

Given the following data;

Mass = 1.01 kg

Force = 2.4N

To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

  • F represents force.
  • m represents the mass of an object.
  • a represents acceleration.

Making acceleration (a) the subject, we have;

Acceleration, a = \frac{F}{m}

Substituting into the equation, we have;

Acceleration, a = \frac{2.4}{1.01}

<em>Acceleration, a = 2.38m/s²</em>

<em>Therefore, the magnitude of the acceleration of the ball at the time of the crash is 2.38 meters per seconds square. </em>
