Answer:
A: The cube of a number less than the square root of the number.
Step-by-step explanation:
None
Explanation:
Mass of boy = 40 kg
Mass of box = 20 kg
Total mass = 60 kg
Initial potential energy = 0 (since height would be 0 initially)
Final potential energy = mgh
Taking g as 10 m/s²,
=> 60 × 10 × 15
= 9,000 J
So, work done = final potential energy - initial potential energy
= 9,000 J
Power = Work/Time
=> Power = 9000/25
=> Power = 360 J/s
or 360 watt.
