A ball is projected perpendicularly from an inclined plane of angle `theta`, with speed 'u' as shown. The time after which the projectile is making angle `45^(@)` with the inclined plane is :

A ball is projected horizontally from an inclined plane with a velocity V, as shown in the figure. It will strike the plane after a time

A particle is projected on an inclined plane with a speed u as shown in (Fig. 5.61). Find the range of the particle on the inclined plane. .

A particle is projected on an inclined plane with a speed u as shown in (Fig. 5.61). Find the range of the particle on the inclined plane. .

A projectile is fired with a velocity v at right angle to the slope inclined at an angle theta with the horizontal. The range of the projectile along the inclined plane is

A projectile is fired with a velocity v at right angle to the slope inclined at an angle theta with the horizontal. The range of the projectile along the inclined plane is

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.
