How much force is exerted to lift 750 kg of water in the well against the force of gravity? How much work is done to lift this water .05m? How does this compart to the work done byt he man in the treadmill?

I don't know what the man on the tread mill has done.

work=m*g*height=750kg*9.8N/kg*.5m
= 750*9.8*.5 joules

To calculate the force exerted to lift the water, we need to use the equation:

Force = mass * gravitational acceleration

In this case, the mass of the water is 750 kg. The gravitational acceleration on Earth is approximately 9.8 m/s².

Force = 750 kg * 9.8 m/s²
Force ≈ 7350 N

Therefore, the force exerted to lift 750 kg of water against the force of gravity is approximately 7350 Newtons.

To calculate the work done to lift the water, we can use the equation:

Work = force * distance

In this case, the force is 7350 N and the distance is 0.05 m.

Work = 7350 N * 0.05 m
Work = 367.5 Joules

Therefore, the work done to lift the water 0.05 m is 367.5 Joules.

Comparing this to the work done by a man on a treadmill would require more information regarding the specifics of the treadmill workout. The work done on a treadmill usually involves moving one's own body weight against the force of gravity and the friction of the treadmill belt. It is difficult to make a direct comparison without knowing the specific parameters of the treadmill exercise.
