Question

Top fuel dragster cars can accelerate from rest down a quarter mile track (400 meters) in under 4 seconds. Assuming constant acceleration, what would the acceleration of a dragster be if it sped down a track in exactly 4 seconds?

Answer 1

Answer:

Its acceleration will be 25m/s^2

Step-by-step explanation:

Distance the drag star moved from rest =400meters

Time taken =4 seconds

Speed= velocity= distance/time= 400m/4 s=100m/s

Acceleration at time 4 seconds will be;

Acceleration = Velocity/time=100/4=25m/s^2
