How much work (in J) must be done to lift a stack of bricks, which has a mass of 600 kg, from the ground to a height of 15 m?

Acceleration due to gravity is 10 m/s2

M g H

Anyone know how to do this?

Mass*Gravity*Height

600kg*15m*9.8m/s^2(gravity)=88,200J

To find the amount of work done, we can use the formula:

Work = Force × Distance

First, we need to calculate the force required to lift the stack of bricks. The force can be found using Newton's second law, which states that force is equal to the mass multiplied by the acceleration.

Force = mass × acceleration

Given:
Mass (m) = 600 kg
Acceleration due to gravity (g) = 10 m/s^2

Plugging the values into the formula, we get:
Force = 600 kg × 10 m/s^2

Now, let's calculate the force:
Force = 6000 N (Newtons)

Now that we have the force, we can find the work done by multiplying it by the distance the bricks are lifted.

Given:
Distance (d) = 15 m

Work = Force × Distance
Work = 6000 N × 15 m

Calculating the work:
Work = 90,000 J (Joules)

Therefore, the amount of work required to lift the stack of bricks to a height of 15 m is 90,000 Joules (J).
