Answer :
Answer:
[tex]36000 miles/h^{2}[/tex] or [tex]0.0028 miles/s^{2}[/tex]
Explanation:
Acceleration is rate of change of speed per unit time. The change in speed is given by deducting the initial speed from final speed. Assuming that the car starts from rest to a top speed of 100 miles per hour, then the change in speed is equivalent to 100-0=100 miles per hour.
Time is given in seconds and converting to hours will be 10/3600
The acceleration will then be
[tex]\frac {100*3600}{10}=36000 miles/h^{2}[/tex]
Alternatively, the change in speed xould be converted to miles per second hence 100/3600 miles per second divided by 10 s then [tex]a=\frac {100}{36000}=0.0027777777777 m/s^{2}[/tex] rounded off as [tex]0.0028 miles/s^{2}[/tex]
