The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.
Problem
At t= 0, the athlete releases the shot with velocity v = 16 m/s.
(a) What are the velocity and acceleration of the shot in terms of normal and tangential components at t = 0.3 s?
(b) Use the relation an = v2/ρ to determine the instantaneous radius of curvature of the shot’s path at t = 0.3 s.
