Question

While mowing your lawn, you push a lawnmower 120. m with a constant force of 300. N. How much work have you done, assuming that all force is in the same direction as the direction of motion? Express your answer in scientific notation.
a)2.5 x 101 J
b)2.50 x 101 J
c)3.6 x 104 J
d)3.60 x 104 J

Answer 1

We have: Work done = Force × Displacement
Here, Force = 300 N
Displacement = 120 m

Substitute their values into the formula:
W = 300 × 120 
W = 36000

In scientific notation, it would be: 3.6 × 10⁴

Finally, option C would be your correct answer.

Hope this helps!
