Physics - Kinematics Question with Solution | TestHub

If u is doubled, angle at which stone strikes the incline remains same.

The stone was projected up the incline.

If angle of projection is changed keeping angle of incline same, still the stone can strike the incline perpendicularly by adjusting speed of projection

Range of stone on the incline is $\frac{2{\mathrm{u}}^2\sin \beta }{\mathrm{g}{\cos }^2\alpha }\cos (\alpha +\beta )$.
