004 10.0 points A 15.2 g mass is attached to a horizontal spring with a spring constant of 3.72 N/m and released from rest with an amplitude of 29.4| em. What is the speed of the mass when it is halfway to the equilibrium position if the surface is frictionless? Answer in units of m / s. 005 10.0 points A 0.702 kg mass is attached to a horizontal spring. The spring is initially stretched by 0.13 m and the mass is released from rest there. Aer 0.54 s, the speed of the mass is zero (for the rst time after being released). What is the maximum speed of the mass? Answer in units of m / s
