A consumer is comparing two new cars. Car A exert 250 horsepower while Car B exerts 300 horsepower. The consumer is most concerned about the peak velocity that the car can reach. If non conservative forces can be ignored, which of the following statements is true?
Correct answer: A. Car A and Car B both have unlimited velocities
- A. Car A and Car B both have unlimited velocities
- B. Car A will reach its peak velocity more quickly than Car B.
- C. Car A will dissipate less energy to the surroundings than Car B.
- D. Car A will have a lower peak velocity than Car B.
Explanation
Option A is correct. In an idealized scenario where non-conservative forces such as friction and air resistance are ignored, both Car A and Car B can theoretically achieve unlimited velocities. The absence of opposing forces means there is no cap on the velocity they could reach as long as power is continuously exerted. Options B, C, and D incorrectly assume limitations or factors that are not present in this idealized scenario. Car B's higher horsepower does not lead to a finite peak velocity in the absence of non-conservative forces, nor does it imply faster or energy-efficient performance when such forces are disregarded.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
