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 April 19, 2022 by Ezee_Notes with no comment Physics Problems Question : 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 (A) t_{1}t_{2}\propto R^{2} (B) t_{1}t_{2}\propto R (C) t_{1}t_{2}\propto \dfrac{1}{R} (D) (C) t_{1}t_{2}\propto \dfrac{1}{R}^{2} Answer : option (B) Solution : Related Previous Post Three balls are dropped from the top of a building with equal speed at different angles. When the ballsstrike ground their velocities are 𝑣1, 𝑣 2 and 𝑣3 respectively, then Next Post A projectile is fired with a velocity 𝑣 at right angle to the slope which is inclined at an angle θ with the horizontal. What is the time of flight?
