) A block of mass 0.10 kg is attached and secured to one end of a spring with spring constant 50 The other end of the spring is secured to a wall. The block is pushed against the spring compresses the spring to a position of -0.04 m. When uncompressed, the end of the spring that is attached to the block is at a position of 2 = 0.00 m . The block-spring system is then released from rest, and the block travels along a horizontal rough track. A motion sensor is placed so that it measures the velocity of the object as it slides along the track. A graph of total mechanical energy of the block-spring system as a function of position is shown. Which of the following statements about the block-spring system are true? Select two answers. O The force exerted on the block by the spring at = -0.02 m is 1N. B) O The block has maximum speed at 0.00 m. O The block has half the initial spring potential energy at <= -0.025 m. O The work done by friction as the block travels from * = -0.04 m to # -0.02 m is 0.01 J.
