Question 1093453
.
<pre>
1.   Your 1,360 kg car accelerates at 2.5 m/s^2 for 4 s. 
     What is the net force applied to produce this acceleration?


     Net force = m*a, the mass multiplied by the acceleration (second Newton law) = 

                 1360 * 2.5 Newtons.  Calculate it on your own.



2.  What is the car's final velocity? (mi/hr)

    Final velocity  V = at = acceleration multiplied by time = 2.5 * 4 m/s.

    Calculate it on your own.  Then convert to miles per hour.

    1 mile = 1609.34 meters.  1 hour = 3600 seconds.



3.  How far does the car move during the acceleration? (in m and ft)

    The distance the uniformly accelerated body travels from the rest for the time t is 

    S = {{{(at^2)/2}}} = {{{(2.5*4^2)/2}}} m/s.

    Calculate it on your own.
