I would like a better Understanding on how to complete the following, please explain. Find the work done by the force F in moving an object from P to Q.
F = 300i + 60j; P(−1, 1), Q(200, 1)

The equation will be:

Why?

Let's work with your friend equation in order to find the time from his house to the restaurant (is the same as yours).

We are given the following function:

When: our friend arrived, so, calculating "x", we have:

We have that it took 5 hours for our friend to arrive at the restaurant, and it's the same time for you. We know that you live 100 miles from the restaurant.

Your equation will have the following form:

Where,

y is the position

k is the rate distance/time

x is the time

Now, again, when , you will have arrived at the restaurant too, so:

Using "x" equal to 5 hours, because you will have arrived at that time too, we have:

Your equation will be:

Have a nice day!
