NEED HELP BADLY!!

A car with an initial velocity of 22 m/s is accelerated at a rate of 7.3 m/s/s for 6.8 seconds. What is the cars final velocity?

Explanation:

initial velocity (u) = 22 m/s

Final velocity = ?

acceleration = 7.3 m/s^2

time = 6.8 sec

Now,

acceleration = final velocity- intial velocity/time taken

7.3 = v-u/t

7.3= v-22/6.8

7.3×6.8= v-22

49.64=v-22

49.64+22 =v

v= 71.64 m/s
