Question

The McLaren F1 is an unusual million dollar car built as a lifetime fascination for racing by a

very successful formula one designer. In its road-legal configuration, the F1 can accelerate
from zero to 100 mi/hr in just over six seconds, beating a Porsche 3.6 Turbo by about four
seconds!
If you round off the numbers so that the car accelerates from rest to 50 m/s in 3.75 sec, how
far will the car travel in that time?

Answer 1

94 meters

Step-by-step explanation:

Use the kinematic equation v₂ = v₁ +at

Because it starts from rest, v₁ = 0, so we get v₂ = at.

Plug in the numbers to get: 50=3.75a

a = 13.3 m/s²

Now use the kinematic equation v₂² = v₁² + 2ad

Plug in the numbers to get: 50² = 2*13.3*d

d = 94 meters
