Change in momentum between point of projection and point of striking on horizontal

An object is projected horizontally from a top of the tower of height h. The line joining the point of projection and point of striking on the ground makes an angle 45^@ with ground, then with what velocity the object strikes the ground

A ball of mass m is projected from the ground with an initial velocity u making an angle of theta with the vertical. What is the change in velocity between the point of projection and the highest point ?

A particle is projected from the ground with an initial speed v at an angle theta with horizontal. The average velocity of the particle between its point of projection and highest point of trajectory is [EAM 2013]

A particle of mass m is projected with velocity v at an angle theta with the horizontal. Find its angular momentum about the point of projection when it is at the highest point of its trajectory.

A particle of mass m comes down on a smooth inclined plane from point B at a height of h from rest. The magni-tude of change in momentum of the particle between position A (just before arriving on horizontal surface) and C (assuming the angle of inclination of the plane as theta with respect to the horizontal) is

A projectile si thrown with velocity of 50m//s towards an inclined plane from ground such that is strikes the inclined plane perpendiclularly. The angle of projection of the projectile is 53^(@) with the horizontal and the inclined plane is inclined at an angle of 45^(@) to the horizonta.. (a) Find the time of flight. (b) Find the distance between the point of projection and the foot of inclined plane.

A ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at a distance a from the point of projection and returns to its original position. Find the coefficient of restitution between the ball and the wall.

When a body is projected at an angle with the horizontal in the uniform gravitational field of the earth, the angular momentum of the body about the point of projection, as it proceeds along its path

A particle of mass m is projected with a speed u at an angle theta to the horizontal at time t = 0 . Find its angular momentum about the point of projection O at time t , vectorially. Assume the horizontal and vertical lines through O as X and Y axes, respectively.

Two parallel straight lines are inclined to the horizon at an angle prop . A particle is projected from a point mid way between them so as to graze one of the lines and strikes the other at right angle. Show that if theta is the angle between the direction of projection and either of lines, then tan theta = (sqrt(2 - 1)) cot prop .
