The position of a weight attached to a spring is s(t) = -2 cos 4t inches after t seconds. Complete parts a)-d) belo a) What is the maximum height that the weight rises above the equilibrium position? in. b) What are the frequency and period? The frequency of the oscillation is cycles per sec. (Type an integer or a fraction. Type an exact answer, using as needed.) The period of the oscillation is sec. (Type an integer or a fraction. Type an exact answer, using it as needed.) c) When does the weight first reach its maximum height? after sec (Type an integer or a fraction. Type an exact answer, using as needed.) d) Calculate and interpret s(1.2). s(1.2)=(Round to the nearest integer as needed.) Interpret s(1.2). Choose the correct answer below. OA. After 2 sec, the weight is about 1.2 in. above the equilibrium position. OB. After 1.2 sec, the weight is about 2 in. above the equilibrium position. 1 OC. After 1.2 sec, the weight is about in. above the equilibrium position.
