A 2-mm-diameter meteor of specific gravity 2.9 has a speed of \(6 \mathrm{~km} / \mathrm{s}\) at an altitude of \(50,000 \mathrm{~m}\) where the air density is \(1.03 \times\) \(10^{-3} \mathrm{~kg} / \mathrm{m}^{3}\). If the drag coefficient at this large Mach number condition is 1.5, determine the deceleration of the meteor.
