11.17 mi
Explanation:
To express the velocity in the S.I. you use the following equality:
then, by replacing you obtain:
When the car has traveled while 15 minutes you have:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
TRANSLATION:
Para expresar la velocidad en el S.I., utiliza la siguiente igualdad:
entonces, al reemplazar, obtienes:
Cuando el automóvil ha viajado durante 15 minutos, tiene:
Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
