Answer:
Power = 130 watt
Explanation:
Power is described as the ability to do work, it is also defined as the amount of work in Joules done in a given time in seconds. Mathematically, it is represented as:
In this example, power is calculated as follows:
Work = 39000 J
Time = 5 minutes
converting the time from minutes to seconds:
1 minute = 60 seconds
∴ 5 minutes = 60 × 5 = 300 seconds
N:B the unit for power can also be represented as Joules/seconds or J/s or JS⁻¹
(i) because there's gravity force pulling it downwards.
(ii) because the force on the metal box is gone (either it has landed on the ground or something else happened) that means that the metal box is no longer moving but it has constant velocity/uniform velocity.
I'm sorry if it's wrong but that's how I see it
