Question

Three cars with identical engines and tires start from rest, and accelerate at their maximum rate. Car X is the most massive, and car Z is the least massive. Which car needs to travel the farthest before reaching a speed of 60 mi/h?
A. Car Z
B. Car Y
C. Car X
D. All cars need to travel the same distance, although some cars will take longer than other cars.

Answer 1

Answer:C) car X

Explanation:

Given

All the cars have identical Engine thus Force Produced by car X will be equal to  Y and Z

and $Force=mass\times acceleration$

Since Car X is most massive so acceleration associated with it will be minimum

acceleration of car X is minimum thus it will travel farthest
