Answer:
Explanation:
Applying Forces, doing Work and developing Power. Applying Forces: Force is a push or a pull and many forces are acting on you all of the time. ... possible to stretch the rubber band with one hand using your thumb and finger at two different places but ... If you are smart, however, just exerting forces, shouldn't get you tired
An object ALWAYS has velocity, although the velocity may be zero for most of the time, or even all the time.
'Velocity' means the object's speed AND the direction in which it's moving.
As long as the girl stands and holds the ball in her hand, the ball's velocity is zero. As soon as she drops it out of her hand, it starts having velocity that's not zero.
While it's bouncing, its velocity is . . .
== growing and downward while it's falling from her hand toward the ground,
== zero for the instant of time when it hits the ground and changes direction from down to up,
== shrinking and upward while it's rising from the ground to her hand,
== zero for the instant of time when it hits her hand and changes direction from up to down.
The answer is B. 1,4, and 6
The force constant of the spring is approximately 24.038 newtons per meter.
As we are talking about Simple Harmonic Motion. In this exercise we need to determine the Spring Constant (
), in newtons per meter, from the equation of the Period (
), in seconds, which is described below:
(1)
Where 
is the mass of the moving element, in kilograms.
If we know that 
and 
, then the spring constant of the spring is:
The force constant of the spring is approximately 24.038 newtons per meter.
