I was helping someone with the following problem...
A projectile is launched from point A at an angle of 25 degrees relative to the horizontal, with initial velocity = 60 ft/s.
Determine the speed of the projectile along its trajectory where its radius of curvature is 3/4 of its radius of curvature at point A.
(Ignore air resistance.)
We both (independently) worked out a speed = 41.6 m/s, however, the book solution has a speed of 54.5 ft/s.
Appreciate it if someone is able to verify the book's solution.
