For a given value of _ the maximum range of a projectile can be achieved by throwing it at an angle of 45°:
Correct answer: B. Initial velocity
- A. Acceleration
- B. Initial velocity
- C. Average acceleration
- D. None of these
Explanation
When a projectile is thrown at an angle of 45°, the maximum range is achieved when the initial velocity is optimized. This is because the horizontal and vertical components of the initial velocity are equal at this angle, leading to the farthest distance traveled before hitting the ground. The other options, such as acceleration and average acceleration, do not directly impact the range of a projectile at a specific angle of projection.

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.
