With regard to rotating limbs to project objects, a relationship exists between the <u>velocity</u> of the rotating arm and the<u> </u><u>velocity</u> of the projected object.
In easy words, velocity is the rate at which something moves in a specific route. For instance, the speed of a car touring north on a highway, or the speed a rocket travels after launching.
Speed (v) is a vector quantity that measures displacement (or change in function, Δs) over the exchange in time (Δt), represented by means of the equation v = Δs/Δt. Velocity (or price, r) is a scalar quantity that measures the space traveled (d) over the trade in time (Δt), represented by using the equation r = d/Δt.
The pace is the directional pace of an item in motion as an indication of its price of alternate in function as observed from a selected frame of reference and as measured by way of a particular preferred time.

Answer:
The answer is to seek optimum levels of arousal.
Explanation:
There is a theory that states that the principal reason that motivates people to make an action is to keep an optimal level of physiological arousal. This optimal level of arousal is different according to the person, as well as it is a very important aspect related to attention and information process.
Thus, maintain the optimal level of arousal is very important concerning the performance that a person can have in a specific task. Research has demonstrated that the psychological factor that is in charge of arousal of motivation is also related to the performance.
