A block is projected up along the line of greatest slope of an inclined plane of angle of inclination `0(ltphi)` where `phi=` angle of friction. Which of the following friction time graph is CORRECT ?

A block of mass m is kept on an inclined plane is angle inclination theta ( lt phi), where phi= angle of friction. Then :

A body is projected up with a speed v_0 along the line of greatest slope of an inclined plane of angle of inclination beta . If the body collides elastically perpendicular to the inclined plane, find the time after which the body passes through its point of projection.
