Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_97

2/97 A football player releases a ball with the initial conditions shown in the figure. Determine the radius of curvature \(\rho\) of the path and the time rate of change \(\dot{v}\) of the speed at times \(t = 1\) sec and \(t = 2\) sec, where \(t = 0\) is the time of release from the quarterback's hand. (Given: Initial speed \(v_0 = 80\) ft/sec at an angle \(\theta = 35^\circ\) above the horizontal).
