How much work is done when a mass of 3 kg (weighing
30 N) is lifted vertically through 6 m?
I guess g = 10 m/s^2
work = force in direction of motion * distance
= 30 Newtons * 6 meters = 180 Joules
To calculate the work done when lifting an object vertically, you can use the equation:
Work = force x distance
Given:
Mass = 3 kg
Weight = 30 N
Distance = 6 m
Since weight is the force acting vertically downwards due to gravity, we can use it as the force in the equation. Therefore:
Work = 30 N x 6 m
= 180 joules
So, the work done to lift the 3 kg mass vertically through 6 m is 180 joules.
To calculate the work done when lifting a mass vertically, we use the formula:
Work = Force x Distance
In this case, the force exerted to lift the mass is equal to its weight, which is given as 30 N.
The distance through which the mass is lifted is given as 6 m.
Therefore, we can calculate the work done as follows:
Work = Force x Distance
Work = 30 N x 6 m
Work = 180 joules
So, the work done when lifting a mass of 3 kg vertically through 6 m is 180 joules.
