Question

a.
5. A car speeds up from 5 m/s to 55 m/s in only 8 s. What is the acceleration of the
car?
a. 6.25 m/s2
b. 62.5 m/s
c. 50 m/s
d. 5.5 m/s​

Answer 1

Answer:

a.6.25m/s

Explanation:

u=5m/s

v=55m/s

t=8s

v=u+at

55=5+8a

a=50/8=6.25

Answer 2

Answer:

a)6.25 m/s

Explanation:

acceleration = change in velocity/time

a=5 - 55/8

a= 50 / 8

a= 6.25 m/s

so acceleration will be 6.25 m/s 2
