The amount of work done by the fork-lift truck in lifting the crate is 2,195.2 Joules.
Given the following data:
Scientific data:
To calculate the amount of work done by the fork-lift truck in lifting the crate:
In Science, work done is generally calculated by multiplying force and the vertical distance or displacement experienced by an object.
Mathematically, work done is given by the formula:
[tex]Work\;done = force \times displacement = mgh[/tex]
Substituting the given parameters into the formula, we have;
[tex]Work\;done = 64 \times 9.8 \times 3.5[/tex]
Work done = 2,195.2 Joules.
