Resultant force and work

The speed of a 4Kg object is given by v=(2t)m/s,where t is in seconds. At what rate is the resultant force on this object doing work at t=1 second?

Solution Preview

Force = m*a (mass times acceleration)

= (4 kg)(2 m/s^2) = 8 N

The acceleration is the first derivative of velocity ...

Solution Summary

This solution is provided in 114 words. It discusses acceleration and velocity in relation to time using derivatives and calculates work with respect to time.
