Show that the maximum range of a projectile in and direction is dest=cribed in the same time in which it would fall freel undr gravity throuth this distance starting from rest.

The ratio of the distance through which a body falls in 4th, 5th and 6th second is starting from rest

An electron falls through a distance of 1.5 cm in a uniform electric field of magnitude 2.0xx10^(4)N//C(Fig.a) Calculate the time it takes to fall through this distance starting from rest. If the direction of the field is reversed (fig .b) keeping its magnitude unchanged , calculate the time taken by a proton to fall through this distance starting from rest.

Assume that the acceleration due to gravity on the surface of the moon is 0.2 times the acceleration due to gravity on the surface of the earth. If R_e is the maximum range of a projectile on the earth's surface, what is the maximum range on the surface of the moon for the same velocity of projection

An electron falls from rest through a vertical distance h in a uniform and vertically upward directed electric field E. the direction of electric field is now reversed, keeping its magnitude the same. A proton is allowed to fall from rest in it through the same vertical distance h.The time of fall of the electron, in comparison to the time of flal of the proton is

Prove that the maximum horizontal range is four times the maximum height attained by a projectile which is fired along the required oblique direction.
