Provide an appropriate response.A baseball is hit when it is 3.1 feet above the ground. It leaves the bat with an initial speed of 150 ft/sec, making an angle of 24° with the horizontal. Assuming a drag coefficient 
find the range and the flight time of the ball. For projectiles with linear drag: x = x0 + 
(1 - e-kt)cos ?, y = y0 + 
(1 - e-kt)sin ? + 
/>(1 - kt - e-kt)where k is the drag coefficient, v0 and ? are the projectile's initial speed and launch angle, and g is the acceleration of gravity (32 ft/sec2). A. Flight time = 3.97 sec; range = 424.4 feet B. Flight time = 3.74 sec; range = 413.5 feet C. Flight time = 2.82 sec; range = 393.5 feet D. Flight time = 3.62 sec; range = 402.2 feet
