Potential energy graph A block on a horizontal frictionless surface experiences simple harmonic motion because it is attached to a horizontal spring. The graph below plots the elastic potential energy stored in the spring as a function of time while the motion is going on. Potential energy vs. time time T1 Part (a) Homework . Answered O Use these numbers: The time T1 shown on the horizontal axis is 0.750 s; the value of E, the maximum energy on the graph, is 0.500 J; and the spring has a spring constant of 20.0 N/m. Calculate the amplitude of the oscillations. m Type your numeric answer and submit 0.224 You are correct Answered - Correct! . 4 attempts left Resubmit Part (b) Homework . Answered Calculate the mass of the block, in grams. grams Type your numeric answer and submit 284 X You are incorrect Answered - Incorrect . 2 attempts left Resubmit
