At highway speeds, a particular car is capable of an acceleration of about 1.6 m/s?. At this rate, does it take the car to speed up from 80 km/hr to 110 km/hr? Round your answer to
Two significant figures

Given parameters:

Acceleration of the car = 1.6m/s

Initial speed  = 80km/hr

Final speed  = 110km/hr

Solution:

Time taken to achieve this speed = ?

Solution:

Acceleration is the rate of change of velocity with the time taken.

  Mathematically;

     a  =

where a is the acceleration

           V is the final velocity

           U is the initial velocity

           T is the time taken

Now make the unknown time the subject of the expression;

      aT  = V - U

         T =  

Convert the given acceleration to km/hr;

       1.6m/s  = 1.6 x  x x = 5.76km/hr

Input the parameters and solve;

       T =  = 5.2hrs

The time taken is 5.2hrs

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
