Question 43

Easy

Figure 1 shows a crane hoisting a concrete block vertically upwards on a construction site.

The crane lifts the block through a vertical height of 1.5 m.

The work done against gravity on the concrete block is 5400 J.

Calculate the weight of the concrete block [2].

Use the equation:

\text{work done} = \text{force} \times \text{distance moved in the direction of the force}
