A farmer is using a rope and pulley to lift a bucket of water from the bottom of a well. The farmer uses a force F1 = 54.5 N to pull the bucket of water upwards at a constant speed. The bucket, when empty, has a mass of mb = 1.1 kg.

(a) Mass of the water in the bucket is .

(b) The volume of water will be

Explanation:

The question is incomplete the complete question is given below.

A farmer is using a rope and pulley to lift a bucket of water from the bottom of a well. The farmer uses a force to pull the bucket of water upwards at a constant speed. The bucket, when empty, has a mass of = 1.1 kg.

(a) Calculate the mass of the water in the bucket, in kg

(b) Calculate the volume of the water in the bucket, in . Use density of the water 1.00 g/

Given the farmer uses a force to pull out the bucket.

Also, the mass of the bucket is

The force due to mass of bucket and mass of water will balance the force used by farmer.

So,

So, mass of the water in the bucket is 4.46 kg.

Now, let us work on next part.

Given density of the water

So, the volume of water will be

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
