Question 3 of 15

Answer 1

Answer:

C. $66.7m/s^{2}$

Step-by-step explanation:

We sholud also talk about medium aceleration

$a_{m} =\frac{V_{f}-V_{i}}{t_{f}-t_{i}} = a_{m}=\frac{54-4}{0.75-0} = 66.7m/s^{2}$

NOTE : $a=(v/t)=\frac{\frac{m}{s} }{s} =\frac{\frac{m}{s} }{\frac{s}{1} }=\frac{m*1}{s*s} = \frac{m}{s^{2} }$ that are acceleration units
