Transcribed Image Text:
A block 4, of mass m is connected through a cable and a pulley to an elastic spring (see figure 3.1). The spring is fixed to the ground and has a spring constant k = 100 N/m. Block A is on an inclined plane forming an angle of 45 degrees with the horizontal line. Block A is released from rest with no slack in the cable and with the spring not being stretched or compressed; assign to m the value in kg of your body weight, then (a) calculate the distance covered by block A once it stops for the first time; assume that there is no friction. (b) describe what happens to block A after it stops for the first time. State all assumptions and comment on your solutions.
