Question

A modern car can develop an acceleration four times greater than an antique car. If both accelerate over the same distance from rest, how does the final velocity of the modern car compare?
Options
A Half as much
B The same
C Twice as much
Correct Answer
D Four times as much
Correct Answer

Option C is the correct answer.

Detailed Explanation

Using v² = 2as. If acceleration is 4a, then v² becomes 4 times larger, so v becomes √4 = 2 times larger.

Hint

Velocity depends on the square root of acceleration.
