SUMMARY
The discussion focuses on calculating the horse-power developed by a motor car with a mass of 2 tons, which accelerates from rest to a velocity of 30 miles per hour in 30 seconds. The correct calculation shows that the engine develops 16.43 horse-power during this time frame. Participants emphasize the importance of using the formula Power = Work-done/Time taken to arrive at the correct answer, and they encourage sharing calculations for further assistance.
