Question 2 A block of mass m = 2 kg at rest is attached to a vertical spring of recall constant k1=70 N/m. Initially, the elongation of the spring is zero and the block is at a height y1 = 1 m from the ground, as shown in the figure below. Released, the block falls on a light platform attached to a second vertical spring, of recall constant k = 60 N/m. Initially, the platform is at a height y2 = 75 cm from the ground and the elongation of the spring of the recall constant k2 is zero ke m YA Y, Feel y=0 a) Using the kinetic energy theorem, find the speed of the block just before contact with the platform b) Using the kinetic energy theorem, find the y position of the block relative to the ground when the second spring is compressed to the maximum.
