The displacement d​ (in meters) of an object at time t​ (in seconds) is given by the following equation. Answer parts​ (a) through​ (d). ​(a) Describe the motion of the object. Is the motion simple​ harmonic? A. ​No, because the given equation is not in the form of . B. ​No, because the given equation is in the form of . C. ​Yes, because the given equation is in the form of . D. ​Yes, because the given equation is not in the form of . ​(b) What is the maximum displacement from its resting​ position? nothing meters ​(c) What is the time required for one​ oscillation? nothing ​second(s)   ​(Simplify your answer. Type an exact​ answer, using as needed. Use integers or fractions for any numbers in the​ expression.) ​(d) What is the​ frequency? nothing oscillations per second   ​(Simplify your answer. Type an exact​ answer, using as needed. Use integers or fractions for any numbers in the​ expression.)
