A car is travelling in a straight line along a highway at a constant speed of 80miles per hour for 10 seconds. Find its acceleration.
Correct answer: C. 0m/s2
- A. 100 m/s2
- B. 200 m/s2
- C. 0m/s2
- D. 150m/s2
- E. 220m/s2
Explanation
The car is traveling at a constant speed, which means there is no change in its velocity. Acceleration is the change in velocity. As there is no change in velocity so the acceleration produced in a var is zero. So option C is the correct answer, while all other options are incorrect

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.
