Abaseball is hit when it is 2.7 feet above the ground. it leaves the bat with n initial speed of 150 ft/sec making an angle of [{mathjax fullwidth='false' 18^{\circ} }] with the horizontal. assume a drag coefficient k=6.12. find the range and the flight time of the ball for projection with linear drag\\ [{mathjax fullwidth='false' x=x_0+ \frac{v_0}{k}(1- e^{-kt}) cos \alpha \\ y= y_0+ \frac{v_0}{k}(1- e^{-kt}) sin \alpha +\frac{8}{k}(1-kt-e^{-kt}) }] where k is the drag coefficient and v_0 and \alpha are the projectiles initial speed and the lauch angle, and g is the acceleration of the gravity (32ft/sec^2) a. flight time=2.93 sec; range=351.6 feet b. flight time=2.81 sec; range=340.3 feet c. flight time=3.16 sec; range=362.5 feet d. flight time=2.01 sec; range=331.6 feet
