Time of flight of a projectile depends upon
Correct answer: C. Launch speed and its angle
- A. Launch angle only
- B. Launch speed only
- C. Launch speed and its angle
- D. Launch height only
Explanation
Launch speed and its angleCorrect. The time of flight (T) is given by the equation:T=2v0sinθ/gThis equation shows that both the initial speed (v0 ) and the launch angle (θ\thetaθ) determine the time of flight.

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.
