Section A: Scenario A small projectile is fired vertically downward into a fluid medium with an initial velocity of v =60 . Due to the drag resistance of the fluid the projectile experiences a deceleration of a = (-0.4v)= m , where v is in - . Determine the projectile's velocity and position 4 s after it is fired.Determine scope of calculus techniques required for this engineering application (Projectile): 1. Identify the calculus technique required for the Projectile scenario. (PC1.1) 2. Develop systematic methods to layout the calculus solution based on the techniques identified in Q1. Identify sources for professional and technical assistance if required to solve the problem. You are required the external (engineer) sign-off of the solution. (PC1.2, 1.4) 3. Identity an appropriate software tool that could be used to provide calculus solution for the above scenario. Provide the solution using the software tool. (PC 1.3)
