A particle of mass m is projected with a velocity v at an angle `60^@` with horizontal . When the particle is at maximum height the magnitude of it's angular momentum about the point of projection is

Two bodies are thrown with the same velocity at an angle 30^@ and 60^@ to the horizontal. What is the ratio of maximum heights reached?

From the top of a cliff 73.5 m a body is projected with a velocity of 19.6 m/s at an angle of 30^@ with the horizontal. Determine the time of flight, the distance from the foot of the tower and velocity with which the body strike the ground. g =9.8 m/ s^2

Two projectiles are fired with same speeds at complimentary angles with the horizontal. Show that the sum of maximum heights achieved by them is independent of the angle of projection.

The horizontal range is four times the maximum height attained by a projectile . The angle of projection is

A projectile is launched with an initial velocity V making an angle with the horizontal. Find an expression for the maximum height to which it will rise and show that it's trajectory is a parabola.

A particle is projected from horizontal making an angle 60^@ with initial velocity 50m/s . The time taken by the particle to make an angle of 45^@ from the horizontal is
