Explanation :

Work is done when a force is applied to create a displacement on an object.

Thus, the work done depends on the two factors i.e.

(1) Applied force (F)

(2) Distance or displacement (d)

Mathematically, work done is

It also depends on the angle between the force and the displacement.

For example,

A person carries a weight of 20 kg and lifts it on his head 1.5 m above the surface. So, the work done by him on the luggage will be:

or

So,

Hence, the work done by him on the luggage is 294 Joules.

By inserting a constant, a statement of proportionality can be turned into an equation. for example, the diameter of a circle is proportional to its radius, ∝ insertion of the constant of proportionality 2, allows one to express this relationship as an equation, = for gases, the constant of proportionality is boltzmann’s constant. use this constant to express the relationship you derived in step 1 as an equation instead of a proportionality. from a text or web resource, find the most common expression of this equation, which is called the ideal gas law.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
