A ball is thrown horizontally with 19.6 m/s. After 2 seconds it's horizontal velocity component will be:
Correct answer: C. 19.6 m/s
- A. 4.9 m/s
- B. 9.8 m/s
- C. 19.6 m/s
- D. 39.2 m/s
Explanation
In projectile motion, horizontal component of velocity remains constant, so horizontal velocity after 2 sec will remain 19.6m/sec. So, correct option is C.

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.
