Question

4. A car accelerates, from rest, at 2.4 m/s?. How fast is the car traveling
after 8 s?
a. 19.2 m/s
b. 3.33 m/s
C. 4 m/s
d. 20 m/s

Answer 1

Answer:

19.2m/s

Explanation:

Assuming that 2.4m/s^2 was the acceleration and not a typo, we can use the equation v=at, where v=velocity, a=acceleration, and t=time,

plug in known varibles,

v=2.4*8

v=19.2m/s
