What is the time of flight? (A) \dfrac{2v^{2}}{g}\tan \theta (B) \dfrac{v^{2}}{g}\tan \theta (C) \dfrac{2v^{2}}{g}\sec \theta (D) \dfrac{2v^{2}}{g}\tan \theta sec \theta Answer : option (A) Solution : Related Previous Post For a given velocity, a projectile has the same range 𝑅 for two angles of projection if 𝑡1 and 𝑡2 are the times of flight in the two cases then Next Post A boy whirl is a stone in a horizontal circle of radius 1.5 m and at height 2.0 m above level ground. The string breaks and the stone flies off tangentially and strikes the ground after traveling a horizontal distance of 10 m. What is the magnitude of the centripetal acceleration of the stone while in circular motion?
