A projectile is thrown from level ground at some angle

A projectile is fired from level ground at an angle theta above the horizontal. The elevation angle phi of the highest point as seen from the launch point is related to theta by the relation.

A projectile is fired from level ground at an angle theta above the horizontal. The elevation angle phi of the highest point as seen from the launch point is related to theta by the relation.

Two projectiles thrown from the same point at angles 60^@ and 30^@ with the horizontal attain the same height. The ratio of their initial velocities is

A projectile is projected from the ground by making an angle of 60^@ with the horizontal. After 1 s projectile makes an angle of 30^@ with the horizontal . The maximum height attained by the projectile is (Take g=10 ms^-2)

A projectile is thrown with velocity v at an angle theta with the horizontal. When the projectile is at a height equal to half of the maximum height,. The vertical component of the velocity of projectile is.

A projectile is thrown with velocity v at an angle theta with the horizontal. When the projectile is at a height equal to half of the maximum height,. The velocity of the projectile when it is at a height equal to half of the maximum height is.

A projectile is thrown with a speed v at an angle theta with the vertical. Its average velocity between the instants it crosses half the maximum height is

A projectile is thrown with velocity v making an angle theta with the horizontal. It just crosses the top of two poles,each of height h, after 1 seconds 3 second respectively. The time of flight of the projectile is

A projectile is thrown with speed 40 ms^(-1) at angle theta from horizontal . It is found that projectile is at same height at 1s and 3s. What is the angle of projection ?

A projectile is projected from ground such that the maximum height attained by, it is equal to half the horizontal range.The angle of projection with horizontal would be
