A weight is attached to a spring and reaches its equilibrium position (x=0). It is then set in motion resulting in a displacement of x=14 cost, where x is measured in centimeters and t is measured in seconds. See the figure shown to the right. Answer parts (a) and (b). (a) What is the spring's displacement when t=0? am (Type an integer or decimal rounded to one decimal place as needed.) What is the spring's displacement when t=? cm (Type an integer or decimal rounded to one decimal place as needed.) 3x What is the spring's displacement when t=? cm 4 (Type an integer or decimal rounded to one decimal place as needed.) (b) What is the spring's velocity when t=0? cm/sec (Type an integer or decimal rounded to one decimal place as needed.) What is the spring's velocity when t cm/sec (Type an integer or decimal rounded to one decimal place as needed.) What is the springle uale 3x
