Find the work w1 done on the block by the force of magnitude f1 = 95.0 n as the block moves from xi = - 5.00 cm to xf = 4.00 cm.

Answer;

= 8.55 Joules

Explanation;

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
