Question

A car traveling at 65 km hr–1 north turns west without a change in speed. The car is moving with: (*) Uniform velocity (*) Acceleration (*) Average velocity (*) None of these​

Answer 1

When the car is moving with uniform velocity, then there is nil acceleration in the motion of the car.

Therefore, the total acceleration of the car is 0.

Answer 2

Answer:

The correct answer is acceleration.

Explanation:

• The car travels at the same speed.
• However, the car changes direction.
• This means that the velocity of the car has changed.
• Since the velocity of the car has changed, the car is under acceleration.
• When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
• The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics.
• Acceleration, like velocity, is a vector quantity.

The car is under acceleration.
