Step-by-step explanation:
Hey there!!
Given,
acceleration (a) = 5 mi/hr^2
Initial velocity (u)= 45mi/hr
Time (t) = 4 hrs.
Now,
Final velocity (v) =?
We have,
[tex]a = \frac{v - u}{t} [/tex]
Putting their values,
[tex]5 = \frac{v - 45}{4} [/tex]
Simplifythem.
20 = v - 45
v = 65.
Therefore, the finalvelocity is 65mi/hr.
Hope it helps....
