2832.6375 watts of power was used

Explanation:

Power is Work over time, so we need to find work first.

Work = Force * Distance, and force is measured in newtons, so we must convert kg to N first.

1kg=9.81N
770kg=7553.7N

Now, we can calculate for work:

w=fd
w=7553.7N*1.5m
w=11330.55J

Since power is just work over time, divide the work used by the time (4 seconds).

(11330.55J)/(4s)=2832.6375 watts
