Question: For the particle of Problem 12.76, determine the tangential component Ft of the central force F along the tangent to the path of the particle

For the particle of Problem 12.76, determine the tangential component Ft of the central force F along the tangent to the path of the particle for

(a) ( = 0,

(b) ( = 45o.

In Problem 12.76,

A particle of mass m is projected from Point A with an initial velocity v0 perpendicular to line OA and moves under a central force F along a semicircular path of diameter OA. Observing that r = r0 cos ( and using Eq. (12.25), show that the speed of the particle is v = v0 / cos2 (?
