The terminal velocity of a person falling through air is about 300km/hr. the acceleration due to gravity is 10ms^? 2. use this information to find out what c is in the equation v? =c(gc? v), where g is the acceleration due to gravity and v is the velocity.(a) how long does it take for a falling person to reach the 90 percent of this terminal velocity? t =(b) how long to reach 95 percent? t =(c) how long to reach 99 percent? t =
