cause an object to accelerate in a direction opposite to the unbalanced force
Explanation:
An unbalanced force is defined as any force that causes an object to accelerate in a direction opposite to the unbalanced force.
The unbalanced force is the net or resultant force describe in newton's second law of motion.
In the first law, it is the external force that causes the motion of a body to change.
Unbalanced forces can cause body to either accelerate in the direction of the force or in an opposite direction of the force.

Answer:
Note that the angle of lap is 165 degrees at the question above
So the power (kW) transmitted when the belt runs at 13 m/s and centrifugal force is included = 3.79782kW
Explanation:
Centrifugal force, Fc = pAv^2
Where p = density, A = c.s.a. v = veelocity
= 11x100 kg/m3 X 4x100 mm2 X (13 m/s)^2
= 1100 kg/m3 X 400 mm2 x 10^-6 X 169m/s
= 74.36N
P v (f - Fc) (1-e^-μθ)
The θ = (165 degrees ÷ 180 degrees) X π = 2.878 rads (π = 3.14)
So power p, = 10 (637 N - 74.36N) (1 - e^-0.39 x 2.878)
= 10 X 562.64 X 0.675
P = 3797.82 watts = 3.79782kW
<u>Statement</u><u>:</u>
A body is under the action of a force F such that the force-displacement graph of the body is semicircle as shown above. The work done on the body by the force in moving through 24 meters.
<u>To </u><u>find </u><u>out</u><u>:</u>
The work done by the body.
<u>Solution</u><u>:</u>
- Here force is F and let us consider the displacement as s.
- We know, work done = Fs.
- Here the area under the curve is Fs, i.e., work done.
- We know, area of a semicircle = where r is the radius.
- Here, radius (r) = 24 m
- Therefore, work done
<u>Answer</u><u>:</u>
The work done is 288π m².
