= 8.55 Joules
Work done is the product of force and the distance moved by an object.
Work done = Force × distance
Force = 95 Newtons
Distance = X2 -X1
= 4 - (-5)
= 9 cm
Thus;
work done = 95 × 9/100
= 8.55 Joules
The work done on a block by the force exerted on it is equal to 8.55 Nm.
Given the following data:
Conversion:
Initial position = -5.00 cm = [tex]\frac{5}{100} = 0.05\; meters[/tex]
Final position = 4.00 cm to m = [tex]\frac{4}{100} = 0.04\; meters[/tex]
To find the work done on a block by the force exerted on it:
First of all, we would determine the displacement of the block.
[tex]Displacement = x_f - x_i\\\\Displacement = 0.04 - (-0.05)\\\\Displacement = 0.04 + 0.05[/tex]
Displacement = 0.09 meters.
Mathematically, work done is given by the formula:
[tex]Work\;done = Force \times displacement[/tex]
Substituting the given parameters into the formula, we have;
[tex]Work\;done = 95 \times 0.09[/tex]
Work done = 8.55 Nm
