The formula of time of flight of projectile(t) is given as _.
Correct answer: A. t=2usinθ/g
- A. t=2usinθ/g
- B. t=sinθ/g
- C. t=2u/g
- D. t=usinθ/g
Explanation
The correct formula for the time of flight of a projectile is t=2usinθ/g. This formula takes into account the initial velocity, angle of projection, and acceleration due to gravity, providing an accurate calculation of the time the projectile remains in the air. The other options either miss one of these crucial components or do not have the correct combination of variables.

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.
