013 (part 1 of 3) 10.0 points A block of mass 585 g is pushed against the spring (located on the left-hand side of the track) and compresses the spring a distance 5.3 cm from its equilibrium position (as shown in the figure below). The block starts from rest, is accelerated by the compressed spring, and slides across a frictionless horizontal track (as shown in the figure below). It leaves the track horizontally, flies through the air, and subsequently strikes the ground. The acceleration of gravity is 9.81 m/s.
