A person leaps from an airplane 5000 feet above the ground and deploys her/his parachute after 7 seconds. Assume that the air resistance both before and after deployment of the parachute results in a deceleration proportional to the person's velocity, but with a different constant of proportionality. Before deployment, take the constant to be 0.16, and after deployment use the value 1.6. (The acceleration due to gravity is 32.2ft/sec^2. Note also that the constants of proportionality given are rho = klm, not k.) a. How fast is the person going when the parachute is deployed? speed = b. How high off the ground is the person when the parachute is deployed? height= c. Approximately (to one decimal place) how much longer does it take the person to reach the ground (give your answer in seconds)?
