A projectile is thrown in the upward direction making an angle of `60^@` with the horizontal direction with a velocity of `150 ms^-1`. Then the time after which its inclination with the horizontal is `45^@` is

A projectile is projected in the upward direction making an angle of 45^@ with horizontal direction with a velocity of 150 ms^(-1) . Then the time after which its inclination with the horizontal is 30^@ is (g=10 ms^(-2)).

A projectle is grojected in the upward direction maging an agnle of 60^@ will horizontal derection with a velocity of 147 ms^(-1) . The the time after which its inclination with the horizontal is 45^@ is.

A projectile is thrown in the upward direction making an angle of 60^@ with the horizontal with a velocity of 140 ms^-1 . Then the time after which its velocity makes an angle 45^@ with the horizontal is (Acceleration due to gravity g=10 ms^-2 )
