1) What is the work done by this force during the time interval?

What is the average power developed by this force during the time interval.

If the object was at rest when x=0, what is the kinetic energy of the object at x=2m

**Henry**, Wednesday, November 13, 2013 at 8:58pm1. F = 250*2 + 25 = 525 N.

Work = F*d = 525 * 2 = 1050 Joules.

2. P = F*d/t = 525 * 2/3 = 350 J/s. =

350 Watts.
