Answer:

Explanation:
First, it is required to model the function that models the increasing force in the +x direction:


The equation is:

The impulse done by the engine is given by the following integral:

![Imp = 161.333\,\frac{N}{s^{2}}\cdot [(3.50\,s)^{3}-(2\,s)^{3}]](https://tex.z-dn.net/?f=Imp%20%3D%20161.333%5C%2C%5Cfrac%7BN%7D%7Bs%5E%7B2%7D%7D%5Ccdot%20%5B%283.50%5C%2Cs%29%5E%7B3%7D-%282%5C%2Cs%29%5E%7B3%7D%5D)

Answer:
It is possible to statically charge objects by rubbing it against carpet fibers, but I'm not sure if that was in the article that you read.
Explanation:
Static charge can build up via carpet fibers.
Depending on whether they where conjoined initially, or where born separately really changes the answer of this question. Although studies show that twins generally have a kinetic link, more practical research says that twins are 25% more likely to both be left handed, which is a recessive gene, they are also more likely to die in child birth, twins are more likely to understand and be biligual, along with many other advantages twins may have.
Answer:
Truck will be at a distance of 720 m
Explanation:
Speed of the truck is given as 90 m/sec
Time for which truck travel t = 10 seconds
We have to find the distance that how much truck travel in 8 sec with speed of 90 m/sec
We know that distance is given by 
So distance traveled by truck in 8 sec will be equal to 
So truck will be at a distance of 720 m
