4. An object's motion is described by the equation d-3sin(8n)- 2. The displacement, d, is measured in meters. The time, t, is measured in seconds. Answer the following questions. Part I: What is the object's position (in meters) at t: 0? (4 points) Part II: What is the object's maximum displacement (in meters) from its 3: 0 position? (2 points) Part III: How much time (in seconds) is required for one oscillation? (2 points) Part IV: What is the frequency (measured in Hz) of this oscillation? (2 points) 10. Find the fourth roots of the complex number z, = 1+ ./3.i. Part 1: Write z1 in polar form. (2 points) Part II: Find the modulus of the roots of z1. (2 points)Part III: Find the four angles that define the fourth roots of the number z1. (4 points) Part IV: What are the fourth roots of z, = 1+ 13 /? (4 points)
