5 meters per second is faster than 720 feet per minute.
5 meters per second is 15 feet per second.
720 feet per minute is 12 feet per second.
You multiply 5 by 3 (3 feet in a meter) to get 15 feet per second.
You divide 720 by 60 (60 seconds in 1 minute) to get 12 feet per second.
15 feet > 12 feet per second.

Answer:
1.) 15.24 J
2.) 7.62 W
Step-by-step explanation:
Given that You do a pull-up, lifting yourself by 0.5 in 2 seconds. If your weight is 600 N,
Convert inches into metres
1 inches = 0.0254 metres
Work done = Force × distance
Work done = 600 × 0.0254
Work done = 15.24 J
Power is the rate at which work is done.
That is,
P = WD / time
Power = 15.24 / 2
Power = 7.62 W
Therefore, 15.24 Joule of work done must be done and 7.62 watt of power output must be required to lift the yourself.
