A missile is fired for maximum range with an initial velocity of 40m//s . If g=10m//s^(2) , the range of the missile is

Choose the correct option (i) The speed of a projectile at its maximum height is half of its initial speed. The angle of projection is 60^(@) . (ii) A missile is fired for maximum range with an initial velocity of 20 m//s , the range of the missile is 40 m . (iii) A ball is projected with a kinetic energy E at an angle of 45^(@) to the horizontal. At the highest point during its flight, its kinetic energy will be E//2 . (iv) An object is projected at an angle of 45^(@) with horizontal. The horizontal range and the maximum height will be in the ratio 4:1

A projectile is thrown with an initial velocity of (xveci + y vecj) m//s . If the range of the projectile is double the maximum height reached by it, then

A shell is fired from a long range gun with an initial velocity u=1000ms^(-1) at an angle 30^(@) to the horizon.How long will the shell be in the air? (g=10.0m s^(-2) )

A projectile is projected from ground with an initial velocity (5hati+10hatj)m//s If the range of projectile is R m, time of flight is Ts and maximum height attained above ground is Hm, find the numerical value of (RxxH)/T . [Take g=10m//s^2 ]
