For a pulley system is used in an auto repair shop to lift a 200 kg engine block 1.5 m out of a car, work is done during this process is mathematically given as

w=3000J

Generally, the equation for work done is mathematically given as

W=mgh

Therefore

W=200*10*1.5

w=3000J

In conclusion, work done

w=3000J
