A car travels leftwards with increasing velocity on a horizontal surface. Which of the following options about the direction of acceleration, the direction of the net force, kinetic energy of the car, and the sign of the net work done by external forces is correct for this situation?
Understand the Problem
The question is asking about the properties of motion for a car traveling leftwards with increasing velocity. It seeks to determine the correct relationships among the direction of acceleration, direction of net force, kinetic energy, and net work done by external forces based on the described scenario.
Answer
D
The correct option is D.
Answer for screen readers
The correct option is D.
More Information
Since the car is moving leftwards with increasing velocity, acceleration and net force are leftward, kinetic energy is increasing, and the work done by external forces is positive.
Tips
A common mistake is mixing up the direction of velocity and force. Ensure to align direction of acceleration with net force.
