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 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.

A body is projected in vertically upwards direction with a speed u. Find the time taken

A body is projected so that it has maxium hoizontal range R.What is the maximum height reached during the flight?

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.

What will be the kinetic energy of a body when its mass is made four times and the velocity is doubled?

Keeping the angle of projection same, what is the effect on horizongal range of a projectile when its velocity is doubled?

A projectile is fired with velocity making an angle theta with the horizontal. Show that it follows a parabolic trajectory. Obtain an expression for the maximum height attained by it.
