Acomet experiences uniform acceleration from 60 m/s to 183 m/s in 10.0 s. what is its rate of acceleration?

a. 6.0 m/s2
b. 12.3 m/s2
c. 18.3 m/s2
d. 24.3 m/s2

Initial velocity of the comet = 60 m/s
Final velocity of the comet = 183 m/s
Time taken by the comet for changing the velocity = 10 seconds
Now
Acceleration = (Final velocity - Initial velocity)/ Time
                     = (183 - 60)/10
                     = 123/10 
                     = 12.3 m/s^2
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that has actually come to your desired help.
