The range of projectile will be maximum if the factor sin20 becomes
Correct answer: B. 1
- A. Zero
- B. 1
- C. -1
- D. 2
Explanation
The range of a projectile is maximized when sin(2θ)=1. This occurs at an angle θ=45.

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.
