Whenever an object is falling, its potential energy
is decreasing and its kinetic energy is increasing.
Olivia's potential energy is decreasing and her kinetic energy
is increasing as she moves toward the right side of the picture,
all the way from W, through X, to the bottom of the arc.
How can I help? What’s the question?
Answer:
i put this in the calculator and my answer is 600. hope this helps
Explanation:
Answer:
<em>Fn = 50 N</em>
Explanation:
<u>Net Force</u>
The net force is the sum of all the forces acting on an object.
When all the forces act in a single line, the direction of the forces is given by their signs. Positive signs are assumed to be up and left on both axes.
The box being raised by a force has a weight of W=-125 N. The negative sign indicates the weight points down. The accelerating force goes up and its value is F=175 N. The positive sign indicates this force pushes the box up.
The forces acting on the box are:
The weight W=-125 N
The accelerating force F=175 N
The net force is
Fn = W + F = -125N + 175 N
Fn = 50 N
Power is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. <span>As is implied by the equation for </span>power<span>, a unit of </span>power <span>is equivalent to a unit of work divided by a unit of time. The formula would be as follows:
P = W/t
We calculate as follows:
500 W = 15000 J / t
t = 30 s</span>
