A car of mass 1000 kg is accelerated from a velocity of 10 m/s to 30 m/s in a time of 5 s.What is the work done during the acceleration (within 5% accuracy;ignore frictional forces)?

Question

Quizplus · Accepted Answer

The work done during acceleration can be calculated using the equation:
Work = (1/2) * mass * (final velocity^2 - initial velocity^2)

Substituting the given values:
Work = (1/2) * 1000 kg * (30 m/s)^2 - (10 m/s)^2
Work = 400,000 J or 4·10^5 J

The closest answer choice within 5% accuracy is D- 4·10^15 J.
