Question 35521
 A sky diver in free fall travels at a speed modeled by
V(t) = 176(1 – e – 0.18 t)
88=176(1-E-0.18T)
1-E-0.18T=88/176=0.5
0.18T=1-E-0.5
HENCE T =(1-E-0.5)/0.18....PLEASE CHECK YOUR FORMULA

ft per second after t seconds. How long will it take for the skydiver to attain the speed of 60 mph (note: 60 mph = 88 ft/sec)?
