A parachutist has a terminal velocity of -176 feet per second. That is, no matter how long a person falls, his or her speed will not exceed 176 feet per second, but it will get arbitrarily close to that value. The velocity in feet per second, v(t), after t seconds satisfies the differential equation v′(t) = 32 - k *v(t). What is the value of k?
