Answer: 40
Explanation:60kg times 2 =120 pounds
power is 40
Answer:
98 W
Explanation:
Power is change in energy over change in time.
P = ΔE / Δt
The change in energy is:
ΔE = mg Δh
ΔE = (60 kg) (9.8 m/s²) (20 m)
ΔE = 11760 J
The change in time is:
Δt = 2 min = 120 s
So the power is:
P = 11760 J / 120 s
P = 98 W
