For a given value of initial velocity, the maximum range of a projectile can be achieved by throwing it at an angle of:
Correct answer: C. 45°
- A. 90°
- B. 60°
- C. 45°
- D. 30°
Explanation
When a projectile is thrown at a 45° angle, it achieves the maximum range possible for a given initial velocity. This is because at this angle, the horizontal and vertical components of motion are balanced in a way that maximizes the distance traveled. Throwing the projectile at angles greater or less than 45° will not result in the maximum range.

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.
