An 8-kg plunger is released from rest in the position shown and is stopped by two nested springs; the constant of the outer spring is k1 = 4 kN/m and the constant of the inner spring is k2 = 12 kN/m. If the plunger is released from the height
h = 600 mm, determine the maximum deflection of the outer spring.
package is dropped from the plane which is flying with a constant horizontal velocity of vA = 150 ft/s at a height h = 1500 ft. Determine the radius of curvature of the path of the package just after it is released from plane at A.
