How much work is done when a mass of 3kg(g=9.8N/kg) is lifted vertically through 6m?

as always, work = force * distance = mgh

3.27N

To calculate the work done, we need to use the formula:

Work = Force × Distance.

In this case, the force can be calculated using the equation:

Force = Mass × Acceleration due to gravity.

Given that the mass is 3 kg and the acceleration due to gravity is 9.8 N/kg, we can calculate the force:

Force = 3 kg × 9.8 N/kg = 29.4 N.

Now that we have the force, we can calculate the work done by multiplying it by the distance:

Work = Force × Distance = 29.4 N × 6 m = 176.4 Joules.

Therefore, the work done is 176.4 Joules.
