A body P of mass m is thrown with velocity u at an angle `30^@` to the horizontal and another body Q is of teh same mass be projected with velocity u at an angle `60^@` to the horizontal .Find the ratio of the horizonta range nd maximum heights of P and Q.

The time of flight of a body projected with initial velocity u at an angle theta is T. What will be th time of flight if thebody is projected with same velocity at an angle (90^@- theta) ?

A body is projected with a velocity u in a direction making angle theta with the horizontal. Show that path of the projectile is a parabola. Find the maximum heighth reached, the time of flight and horizontal range.

When a projectile os projected at an angle with the horizontal, find the angle of projection for its maximum horizontal range and find the correspondg height achieved by the projectile?

What are the two angles of projection of a projectile with velocity 30 m s^-1 , so that the horizontal range is 45 m.Take g=10 m s^-2 .

If u is the velocity of projection ,what is the value of maximum horizontal range?

A charge q of mass m moving with velocity v, at right angles to a uniform magnetic field B. Deduce the expression for the radius of the circular path it describes.

In the figure, a body A of mass m slides on plane inclined at angle theta_1 to the horizontal and mu_1 is the coefficient of friction between A and the plane. A is connected by a light string passing over a fictionless pulley to another body B, also of mass m, sliding on a frictionless plane inclined at angle theta_2 to the horizontal which of the following statements are true ?

A bullet of mass m fired at 30^@ to the horizontal leaves the barrel of the gun with a velocity v. The bullet hits a soft target at a height h above the ground while it is moving downward and emerges out with half the kinetic energy it had before hitting the targtet. which of the following statements are correct in respect of bullet after it emerges out of the target?
