Let u(t) and w(t) be the horizontal and vertical components, respectively, of the velocity of a batted baseball:

??=−?? and ??=−?−?? ?? ??

where ? is the coefficient of air resistance and g is the acceleration of gravity.

Determine u(t) and w(t) assuming the following initial conditions: ?(0) = ? cos ? and ?(0) = ? sin ?,where V is the initial speed of the ball, and A is its initial angle of elevation.
Let x(t) and y(t) be the horizontal and vertical coordinates, respectively, of the ball at time t. If?(0) = 0 and ?(0) = h, find x(t) and y(t) at any time t.
Plotthetrajectoryoftheballfor?=1/5,V=125ft/s,h=3ft,A=0.5rad,andg=32ft/s2.
Suppose that the outfield wall is at a distance L and has height H. Assuming that ? = 1/5, h = 3, L =

300 ft, and H = 10 ft, find the minimum initial velocity V and the optimal angle of elevation A for which the ball will clear the wall.
