Question

Here we leam how to apply the force shown in the figure (Figure 1) moves an object nz0 to z 0.75 m. You may want to review ges 208-212) How much work is done by the force # the object moves from z-0.15 m to z 0.60 m ? 1 of 1 w.

incase you can’t see the question, it says : How much work is done by the force if the object moves from x= 0.15m to x= 0.60m?

(express your answer using two significant figures)

Answer 1

Use equation,

W= F*d

W_net = W_{from 0.15m to 0.25m} + W_{from 0.25m to 0.50m} + W_{from 0.50m to 0.60m}

W_net = F₁d₁ + F₂d₂ + F₃d₃

W_net = 0.6N*(0.25m-0.15m) + 0.4N*(0.50m-0.25m)*0.8N*(0.60m-0.50m)

W_net = 0.24 J
