Question

For the particle of Prob. $12.74$, determine the tangential component $F_t$ of the central force $\mathbf{F}$ along the tangent to the path of the particle for $(a) \theta=0$, (b) $\theta=45^{\circ}$.

Solution

VerifiedStep 1

1 of 4$\textbf{Knowns}$:

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 $r = r_o \cos\theta$ and using Eq. (12.25),
