x=(0.23m) cos(0.5pit) assue t is in seconds
MY NOTES PRACTICE ANOTHER The position of a 0.30-kg object attached to a spring is described by *-(0.23 m) cos(0.5er). (Assume r is in seconds.). (a) Find the amplitude of the motion 0.23 (b) Find the spring constant. 0.76 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four accuracy to minimize roundoff error. N/m (c) Find the position of the object at t-0.36% 0.2299 x Your response differs from the correct answer by more than 10%. Double check your calculations m (d) Find the object's speed at t= 0.36 0.01005 x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s Need Help? Fea
