Question

The acceleration of a Tesla car that maintains a constant velocity of 120 km/h over a time of one-half hour is?

Answer 1

Answer:

Zero

Explanation:

Acceleration = Change in velocity / Time taken

= (120 kmph - 120 kmph) / (one half hour)

= 0

The car maintains constant velocity, hence its acceleration is zero.

Answer 2

The acceleration of a car is 0 over a time of one-half hour.

Explanation:

Given that,

The velocity of a Tesla car is constant i.e. 120 km/h. It means that the change in velocity of the car is equal to 0. We know that the rate of change of velocity is called acceleration of an object. If change in velocity is zero. It implies that the acceleration of the Tesla car over a time of one-half hour is equal to 0.
