A block at the bottom of an inclined plane is given an initial speed of 4 m/s up the plane. If there is no friction between the plane and the block, how long does it take for the block to return to the bottom?
since the angle of inclination of the plane was not given in the question. So i assumed it to be 'theta' . If you want answer for some specific angle then you can put the value of angle at the place of 'theta' .
