When a stone is projected with `25^(@)` & `65^(@)` to the horizontal, its heights are 1m and 4m respectively. Then its range is

The base and height of a triangle are 12 m and 8 m respectively. Its area is

A stone is projected at 30^(@) above to the horizontal with a speed 20m s^(-1) from the top of a tower of height 120m .The time after which it reaches the ground is (g=10m s^(-2) )

A stone is projected with a velocity 20sqrt2 m//s at an angle of 45^(@) to the horizontal.The average velocity of stone during its motion from starting point to its maximum height 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
