Test Score: 25%, 25 of 100 Question 6, 5.4.4 points ( Points: 0 of 10 A body with mass of 200 g is attached to the end of a spring that is stretched 20 cm by a force of 4 N. At time t=0 the body is pulled 1 m to the left, stretching the spring, and set in motion with an initial velocity of 24 m/s to the right. (a) Find x(t) in the form C cos (mot u) . (b) Find the amplitude and the period of motion of the body. =) (a) x(t) = 2.6000 cos (10t1.9656) . (Use integers or decimals for any numbers in the expression. Round to four decimal places as needed.) (b) The amplitude is 26000 m. 3 (Round to four decimal places as needed.) | - \" The period is 5 S. (Type an exact answer.)
