SUMMARY

The discussion focuses on calculating the average power delivered by a 1300 Kg sports car that accelerates from rest to 95 km/h in 7.3 seconds. Key equations utilized include acceleration (a = Δv/Δt), force (F = ma), work (w = f*d), and power (p = w/t). The average power can be determined by first calculating the force required for acceleration, then the work done, and finally the power output using the time interval. The final answer should be expressed using two significant figures.

PREREQUISITES
  • Understanding of basic physics concepts such as force, work, and power
  • Familiarity with the equations of motion
  • Knowledge of unit conversions, particularly from km/h to m/s
  • Ability to perform calculations involving significant figures
NEXT STEPS
  • Calculate acceleration using the formula a = Δv/Δt
  • Determine the force exerted by the car using F = ma
  • Calculate the work done using the formula w = f*d, where d is the distance covered
  • Compute the average power using p = w/t
USEFUL FOR

Physics students, automotive engineers, and anyone interested in performance metrics of vehicles will benefit from this discussion.

A 1300 Kg sports car accelerates from rest to 95 km/h in 7.3 sec..

What is the average power delivered by the engine?
express answer using 2 significant figures.

cannot figure this out.. any help would be great!
thanks,
Brandon

the relavent equations?

a = Δv/Δt

F = ma

w = f*d

p = w/t
