Answer:
Explanation:
From the question, acceleration from in 10 seconds.
Acceleration function can be written as:-
From the acceleration equation, we can obtain the velocity equation:
We calculate velocity after 10sec from the above v(t) as .
To obtain distance travelled after 10 seconds:-
Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
