An initially stationary 2.7 kg object accelerates horizontally and uniformly to a speed of 16 m/s in 3.1 s. In that 3.1 s interval, how much work is done on the object by the force accelerating it?
What is the instantaneous power due to that force at the end of the interval?
What is the instantaneous power due to that force at the end of the first half of the interval?
