1. Repeat above question if the mass M is normally distributed with mean µ M = 1 slug and standard deviation σ M = 0.25 slugs. Assume B and K are no longer random, instead B=2 lb s/ft and K = 4 lb/ft....

1. Repeat above question if the mass M is normally distributed with mean µ_M
= 1 slug and standard deviation σ_M
= 0.25 slugs. Assume B and K are no longer random, instead B=2 lb s/ft and K = 4 lb/ft.

2. Suppose the arrow and target with mass and aerodynamic properties given in the text are dropped from an airplane in level flight at a cruising speed of v_cr
= 600 ft/s. a. Find expressions for the terminal velocities of both. b. Simulate their descent from an altitude of 10,000 ft with zero initial velocity. c. Plot the acceleration of each during their descent.
