Muscle contractions have increased force at slower shortening velocities compared to higher shortening velocities.
When you perform an activity, your muscles tighten, shorten, or lengthen as a result of the contraction. When you stretch or lift weights, hold anything in your hands, or pick something up, it may happen. Muscle relaxation, when contracted muscles return to their pre-contracted state, is frequently followed by muscle contraction.
The pace at which a muscle shortens during a contraction is known as the shortening velocity. With increased speed, a muscular contraction loses force. Myosin heads attach to actin and pull the actin inward, shortening the muscle.

Based on the calculations, the average velocity of this ball is equal to 0.45 m/s.
<h3>How to calculate average velocity of this ball?</h3>
In order to calculate average velocity of this ball, we would determine the slope of the ball between the given time intervals:

Substituting the given parameters into the formula, we have;
Slope = 5.2/11.5
Slope = 0.45 m/s.
Therefore, the average velocity of this ball is equal to 0.45 m/s.
