Answer:

b. (4677)

Explanation:

You can apply the same equation we use to calculate the compound interest but with phones.

Look:

M = C.(1+i)^n

M = the total amount after 5 years

C = the firts amout of phones (285)

i = how much this number gets bigger (75%)

n = the number of periods (5 years)

So...

M = 285 . (1 + 0,75)^5

M = 285 . 1,75^5

M = 285 . 16.4

M = 4677

A can of sardines is made to move along an x axis from x = 0.47 m to x = 1.20 m by a force with a magnitude given by F = exp(–8x
sattari [20]
If the force were constant or increasing, we could guess that the speed of the sardines is increasing. Since the force is decreasing but staying in contact with the can, we know that the can is slowing down, so there must be friction involved.
Work is the integral of (force x distance) over the distance, which is just the area under the distance/force graph.
The integral of exp(-8x) dx that we need is (-1/8)exp(-8x) evaluated from 0.47 to 1.20 .

I get 0.00291 of a Joule ... seems like a very suspicious solution, but for an exponential integral at a cost of 5 measly points, what can you expect. On the other hand, it's not really too unreasonable. The force is only 0.023 Newton at the beginning, and 0.000067 newton at the end, and the distance is only about 0.7 meter, so there certainly isn't a lot of work going on. The main question we're left with after all of this is: Why sardines ? ?

The added weight of the sand puts more downward pressure on the wheels contacting the rails, which would cause the trains speed to decrease.
