(Your three answers should be identical.) Answer in units of J. 020 (part 1 of 3) 10.0 points A block starts at rest and slides down a fric- tionless track. The acceleration of gravity is 9.81 m/s2 . It leaves the track horizontally, striking the ground (as shown in the figure above). 496 g K 9.81 m/s2 2.5 m K K 5.2 m Ka.) At what height h above the ground is the block released? Answer in units of m
