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 = 10 cos t, where x is measured in centimeters and t is measured in seconds. See the figure shown to the right. Answer parts (a) and (b). I (a) What is the spring's displacement when t=2? cm (Type an integer or decimal rounded to one decimal place as needed.) I What is the spring's displacement when t=? 3 4 cm (Type an integer or decimal rounded to one decimal place as needed.) 5x ary ? What is the spring's displacement when t = - 5 What is the spring's displacement when t = ? 4 cm (Type an integer or decimal rounded to one decimal place as needed.) I (b) What is the spring's velocity when t = 2 cm/sec 4 (Type an integer or decimal rounded to one decimal place as needed.) T What is the spring's velocity when t = ? 3? T What is the spring's velocity when t= 3? cm/sec (Type an integer or decimal rounded to one decimal place as needed.) 5ะป What is the spring's velocity when t = ? 4 cm/sec (Type an integer or decimal rounded to one decimal place as needed.)
