A particle is projected horizontally as shown from the rim of a large hemispherical bowl. The displacement of the particle when it strikes the bowl the first time is R. Find the velocity of the particle at that instant and the time taken.

If the time-displacement graph of a particle is parallel to time-axis, the velocity of the particle is

The displacement-time graph for two particles is as shown. Find the ratio of their velocities.

The displacement time curve of a particle is shown in the figure. The external force acting on the particle is :

A particles is projected horizontally with a speed v from the top of a plane inclined at an angle tehta to the horizontal as shown in the figure. (a) Hwo far from the point of projection will the particle strike the plane ? (b) Find the time taken by the particel to hit the plane. (c) What is the velocity of particle just before it hits the plane ?
