A ball is projected on smooth inclined plane in direction perpendicular to line of greatest slope with velcoity of `8m//s`. Find it's speed after `1sec`.

Find range of projectile on the inclined plane which is projected perpendicular to the incline plane with velcoity 20m//s as shwon in figure.

A uniform solid cylinder of mass M and radius R rolls a rough inclined plane with its axis perpendicular to the line of greatest slope as shown in figure-5.75. As the cylinder rolls it winds up a light string which passes over a light and smooth pulley and attached to a mass m , the part of the string between pulley and cylinder being parallel to the line of greatest slope. Prove that the tension in the string is T = [((3 + 4 "sin"theta) M"mg")/(3M + 8m)]

A small ball is projected up a smooth inclined plane with an initial speed of 10 m//s along the direction at 30^(@) to the bottom edge of the slope. It returns to the edge after 2s. The ball is in constant with the inclined plane throughout the process. What is the inclination angle of the plane?

A ball is projected form a point A on a smooth inclined plane which makes an angle a to the horizontal. The velocity of projection makes an angle theta with the plane upwards. If on the second bounce the ball is moving perpendicular to the plane, find e in terms of alpha and theta . Here e is the coefficient of restitution between the ball and the plane.
