A small airplane flying horizontally with a speed of 161 mi/hr at an altitude of 275 ft above a remote valley drops an emergencymedical package at A. The package has a parachute which deploys at B and allows the package to descend vertically at the constantrate of 6.5 ft/sec. If the drop is designed so that the package is to reach the ground 29 seconds after release at A, determine thehorizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B.В.Target-L161 mi/hrA1275'

A particle P of mass m = 3 kg arrives at point O with a horizontal velocity and starts rolling down a circle with radius R = 1.5 m. The particle is attached to the point O by means of a linear spring of stiffness k = 50 N/m that is unstretched when the particle is at O. Assume that during the motion of P along the circle, the spring follows the circle. Let N = {x, ây} be a fixed reference frame as shown in the figure and let B = {bx, by} be a reference frame attached to P so that b is tangent to the circular path and by is perpendicular to the circular path. For convenience, take g = 10 m/s² in this question. ny ĤT IP
