A 6 kg particle moves right on a straight horizontal track with initial speed \(\displaystyle \frac{5m}{s}.A\) constant drive 18 N acts right and constant resistance 6 N acts left throughout a displacement 4 m. All other forces do no work.

Find work done by the driving force in J.

Enter one exact number or fraction unless the question specifies rounding. Use the requested units and positive direction; enter the number without its unit. Angles here use degrees. Give full reasoning separately for written problems.
