In a projectile motion the velocity

During a projectile motion if the maximum height equal the horizontal range, then the angle of projection with the horizontal is :

Assertion: The maximum horizontal range of projectile is proportional to square of velocity. Reason: The maximum horizontal range of projectile is equal to maximum height attained by projectile.

Assertion : If time of flight in a projectile motion is made two times, its maximum height will become four times. Reason : In projectile motion H prop T^2 , where H is maximum height and T the time of flight.

If the horizontal range of a projectile be a and the maximum height attained by it is b, then prove that the velocity of projection is

Two projectile are projected which have the same range, if first projectile is projected at 30 degrees and its maximum height is h then the maxium height of other projectile is

Assertion In projectile motion, if time of flight is 4s, then maximum height will be 20 m. (Take, g = 10 ms^(-2)) Reason Maximum height = (gT)/(2) .

The direction of the oblique projectile becomes horizontal at the maximum height. What is the cause of it ?

A projectile is thrown with an initial velocity of (a hati + hatj) ms^(-1) . If the range of the projectile is twice the maximum height reached by it, then
