How much power is lifted if a person lifts 60N weight up 2 meters in 10 seconds?
work = f * d = 60 * 2 = 120 J
power = work / time = 120 / 10 = 12 W
work is in Joules and power is in Watts
To calculate the amount of power used to lift an object, we need to use the formula:
Power = Work / Time
The work done is calculated by multiplying the force applied to lift the weight by the distance over which the weight is lifted. So the formula for work is:
Work = Force × Distance
Given:
Force = 60 N
Distance = 2 m
Time = 10 s
First, let's calculate the work done:
Work = Force × Distance
= 60 N × 2 m
= 120 N·m (or Joules)
Now we can calculate the power:
Power = Work / Time
= 120 N·m / 10 s
= 12 N·m/s (or Watts)
Therefore, the power required to lift a 60 N weight up a distance of 2 meters in 10 seconds is 12 Watts.
