Question

12.
An inclined plane makes an angle 0 = 45° with horizontal. A stone is projected normally from the inclined
plane, with speed u m/s at t=0 sec. x and y axis are drawn from point of projection along and normal to
inclined plane as shown. The length of incline is sufficient for stone to land on it and neglect air friction. Match
the statements given in column I with the results in column II. (g in column Il is acceleration due to gravity)
So=45°
