Question

A car and a delivery truck both start from rest and accelerate at the same rate. However, the car accelerates for twice the amount of time as the truck. What is the traveled distance of the car compared to the truck?
Options
A Half as much
B The same
C Twice as much
D Four times as much
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Distance is proportional to the square of time for constant acceleration, so twice the time gives four times the distance.

Hint

Use the kinematic equation s = ut + (1/2)at², starting from rest.
