Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 3) 10.0 points A block is pushed against the spring with spring constant 9 . 1 kN / m (located on the left- hand side of the track) and compresses the spring a distance 4 . 6 cm from its equilibrium position (as shown in the figure below). The block starts at rest, is accelerated by the compressed spring, and slides across a fric- tionless 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 2 . b b b b b b b b b b b b 421 g 2 . 2m x 9 . 81m / s 2 v 9 . 1 kN / m 4 . 6 cm What is the speed v of the block when it leaves the track? Answer in units of m / s. 002 (part 2 of 3) 10.0 points What is the horizontal distance x the block travels in the air?...
