Question

Calculate the amount of work done if you use a 100N force to push a 50kg box 5m across the kitchen floor.

Answer 1

So if the formula for work is force times displacement times cosine(theta), you'd plug in the numbers

100x5 (since there's no angle in the problem, cosine(theta) isn't used

100x5 = 500

So the answer would be B.

Hope that helps!

Answer 2

We know, W = F * s
Here, F = 100 N
s = 5 m

Substitute their values, 
W = 100 * 5
W = 500 J

In short, Your Answer would be Option B

Hope this helps!
