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.
  No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velo â¦ city is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east).A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed.A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed.
