ques1. if the radial and transverse velocities of a point are always proportional to each other and this holds for acceleration also, prove that velocity will vary as some power of the radius vector .

ques2. prove that the path of a point which possesses two constant velocities, one along a fixed direction and the other perpendicular to the radius vector drawn from fixed point, is a conic section .
