How do I go about answering #7 with both Matlab and hand calculations?

Homework 1: Roots of Non-Linear Equations A Parachute Example A parachustist falls from rest. The falling velocity, v is given by the equation below as a function of time. with kg s- and 1. What is the Independent Variable? (2 points) 2. What is the Dependent Variable(s)? (2 points) 3. What are the System Parameters? (2 points) 4. Assume mass, m -80kg. Use the incremental search method to find the time at which the 35m velocity is s. Note: Limits for time t variable: 0 st s 10 (seconds). (23.5 points) 5. Assume mass, m -80kg. Use the bisection method to find the time at which the velocity is 35 .Note: Limits for time t variable: 0sts 10 (seconds). (23.5 points) at t = 78 6. Use the incremental search method to find the mass such that the velocity is 30 s Note: Limits for mass m variable: 1 s m s 201 (kg). (23.5 points) 7. Use the bisection method to find the mass such that the velocity is 50%, at t-7s Note: Limits for mass m variable: 1 s m s 201 (kg). (23.5 points)
