Answer:
Work done = 600 J
Power used = 60 W
Explanation:
Given:
Force acting on the box is,
Displacement of the box is,
Time taken for the work,
Now, we know that, work is said to be done by a force only when there is displacement caused by the force in its direction.
Here, the force acting on the box causes a displacement of 30 m in its direction. So, work done is equal to the product of force and displacement caused.
Therefore, work done on the box is given as:
Therefore, the work done is 600 J.
Now, we know that, power is given as work done per unit time.
So, power used is given as:
Therefore, the power used is 60 W.
The equation : y=3x-5
<h3>Further explanation </h3>Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates
General formula
y-y1 = m(x-x1)
or
y = mx + c
Where
m = straight-line gradient which is the slope of the line
x1, y1 = the Cartesian coordinate that is crossed by the line
c = constant
The formula for a gradient (m) between 2 points in a line
m = Δy / Δx
