Block A (with mass of 300 kg) is connected to a spring with undeformed length of 4 m and spring constant of k = 700 N/m. A strong worker then uses a rope to pull the block 3 m to the right such that the spring is stretched to a length of /= 7 m. The worker stops at this position, such that the block is at rest at this particular instant. The worker then accidentally lets go of the rope, causing the block to begin moving to the left. The coefficient of sliding friction between the block and the horizontal surface is μk = 0.1. 1 k www A Hk W!!!! ← VA d
