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 bullet is fired from a cannon with velocity 500 m/s. If the angle of projection is 15^(@) and g = 10m//s^(2) . Then the range is

A particle is projected from the ground with an initial velocity of 20m//s at an angle of 30^(@) with horizontal. The magnitude of change in velocity in a time interval from t=0 to t=0.5s ( g=10m//s^(2) )

A shell is fired from canon with a velocity of 200 m/s at an angle of 30^@ with the horizontal The horizontal range attained by it is [g= 10 m s^-2]

A body is projected with an initial elocity 20m/s at 60° to the horizontal. The displacement after 2 s is
