When the effect of aerodynamic drag is included, the y-acceleration of a baseball moving vertically upward is a = -g- kv², while theacceleration when the ball is moving downward is ad=-g+kv², where k is a positive constant and v is the speed in meters per second. Ifthe ball is thrown upward with an initial speed of 30 m/s, determine the time tu from ground to apex and the time to from apex toground. Take k to be 0.007 m¹ and assume that g is constant.au=-g-kv²yAnswers:tu=t₁ =ii30 m/sad=-g+kv²SSh

The detailed solution is following.

You have been daydreaming while studying, and watching student pilots take lessons at the Columbus airport. A plane flying at a constant 177.5 m/s suddenly stalls. If the acceleration during the stall is 9.8 m/s² directly downward, the stall lasts 15.8 s, and the plane was initially climbing at 35.5 degrees above the horizontal, what is the speed of the plane at the instant that the stall ends?
