What is the rate of acceleration for a car that reaches a speed of three meters per second from rest in ten seconds? A) 3 meters per second B) 3 m/s² C) 0.15 meter per second D) 0.3 meters per second E) 30 m/s²

Question

Quizplus · Accepted Answer

We can use the equation:

acceleration = (final velocity - initial velocity)/time

Here, initial velocity is 0 m/s since the car starts from rest. Final velocity is 3 m/s. Time taken is 10 seconds.

Therefore,

acceleration = (3 m/s - 0 m/s) / 10 s = 0.3 m/s²

So, the rate of acceleration for the car is 0.3 meters per second (D).
