Answer:
B. ll
Explanation:
A toy car when whirled has a uniform speed and moved in a circular path is said to be accelerating. According to the second Law of motion, which is the law of acceleration that states that an object will accelerate when there is a net or unbalanced force acting upon on it. In this manner, there is acceleration when the speed or the direction changes.
Even if the car is in circular pathway and having uniform or constant speed, the direction of the car varies or changes as it moves. In this case, the velocity of the car changes thus, it means that it is accelerating. Remember that an object in a uniform circular motion may not change its speed but it changes its velocity as the direction of the object changes. The force that is acting upon the object in a circular motion is called the centripetal force.
