A particle of mass m is projected from point A with an initial velocity v0 perpendicular to line OA and moves under a central fo
rce F along a semicircular path of diameter OA. Observing that r = r0 cos θ and r 2 q = h, show that the speed of the particle is v = v0 /cos2 θ

Suppose we choose a path along the
On the other hand, let's consider an arbitrary line through the origin,
The value of the limit then depends on
