The person's speed is 2 meters per second. The power required for him to accomplish that depends on his weight, on his efficiency of movement, on whether he's moving horizontally or vertically, etc., all of which the question neglects to specify.

The work required to move the truck is 600 N (600 kg-m/sec2) times 30 meters = 18000 joules. If this is done in 15 seconds, the average power was 1200 watts (kg-m2/sec3).

If it takes 150 N of force to move a box 10 meters, 1500 joules (J) of work is done. This can also be expressed as 1.5 kilojoules (kJ).
Mass wasting, which includes landslides, can move incredible amounts of sediments in only seconds.
