Provide an appropriate response.A baseball is hit when it is 2.7 feet above the ground. It leaves the bat with an initial speed of 151 ft/sec, making an angle of 22° with the horizontal. Assuming a drag coefficient 
how high does the ball go, and when does it reach maximum height? For projectiles with linear drag: x = x0 + 
(1 - e-kt) cos ?, y = y0 + 
(1 - e-kt) sin ? + 
style="vertical-align: -21.0px;" />(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. Maximum height = 8.27 feet; time to maximum height = 0.74 sec B. Maximum height = 3.03 feet; time to maximum height = 0.06 sec C. Maximum height = -0.23 feet; time to maximum height = -0.21 sec D. Maximum height = 3.07 feet; time to maximum height = 0.02 sec
