3 [2] A baseball player releases a ball with the initial conditions shown in the figure. Determine the radius of curvature of the trajectory (a) just after release, and (b) at the apex (highest point in the ball's trajectory). For each case, compute the time rate of change of the speed. Also, find the horizontal distance travelled by the ball when it reaches the apex. U=100 ft/sec (33 points) 8=30°
