To improve his the jumping record, the long jumper should jump at an angle of:
Correct answer: B. 45o
- A. 30°
- B. 45o
- C. 60o
- D. 90o
Explanation
The following is the solution: Option B is correct because a long jumper should jump at an angle of 45 degrees to maximize the horizontal distance covered and improve the jumping record.

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.
