Problem 4: throwing an apple straight up with drag for reference see events finding and odes pdf document on assignment drag force is a vector in the opposite direction of an objects velocity vector. which means the governing differential equations of an apple thrown straight up can be modeled with a piecewise differential. = − − cc ∗ � � 2 while the ball is apple is rising = − + cc ∗ � � 2 while the ball is apple is falling where g is the acceleration due to gravity (9.8 m/s2 ) and c is the drag coefficient. use odeset, "events" with ode45 to find how long an apple will be in the air if: • it is thrown straight up from an initial height of 2.5 m • it has an initial velocity of 10 m/s • c = 0.1

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
