B. 10,400 N D. 399 N. C___ 2. If a car is moving to the left with constant velocity, one can conclude that. A. there must be no forces applied to the car. B. the net force applied to the car is directed to the left. C. the net force applied to the car is zero. D. there is exactly one force applied to the car. A___ 3.
Answer is NO. If I am walking along a road as I normally do at a constant velocity of 2.5m/s. my velocity is constant, but not zero, and my acceleration is zero. Like wise if I drive my car as I usually do along the highway at a constant velocity of 15m/s, My acceleration is zero. But my velocity is not zero. The converse: In free flight, the acceleration of any object is always 9.81m/sÂ² downwards. It never changes. If I throw a ball up into the air at its highest altitude, as it changes from going up to coming down, the velocity is zero, but the acceleration downwards due to gravity is still as it always is , 9.81m/sÂ³.
