If 2.0 J of work is done in raising a 280g apple, how far is it lifted?
I would say F= 2.0/180 but that doesn't really sound right...
To determine how far the apple is lifted, we can use the formula for work done:
Work = Force × Distance
In this case, we have the work done (2.0 J) and the mass of the apple (280g). We need to find the distance.
First, let's convert the mass to kilograms: 280g ÷ 1000 = 0.280 kg.
Now, we can find the force by multiplying the mass (0.280 kg) by the acceleration due to gravity (9.8 m/s²):
Force = 0.280 kg × 9.8 m/s² = 2.744 N.
Finally, we can rearrange the formula for work to solve for distance:
Distance = Work ÷ Force
Plugging in the values, we have:
Distance = 2.0 J ÷ 2.744 N ≈ 0.73 meters.
Therefore, the apple is lifted approximately 0.73 meters.
