Hello. I need the answers for the following questions.

Position (centimeters) 0 2 4 6 B 10 12 Time (seconds) The plot shows the position versus time of a mass of 1.2 kg on a spring. What is the spring constant? : The graph shows the xdisplacement as a function of time for a particular object undergoing simple harmonic motion. 6 1 2 3 4 5 6 7 8 916111213141516 tts) This function can be described by the following formula: x(t) = Acos(wt), where x and A are measured in meters, t is measured in seconds, to is measured in rad/s. Using the graph determine the amplitude A of the oscillation. Tries 9/99 Determine the period T of the oscillation. Tries 9/99 If the mass of the oblect is 40.3 Q, then what is the total mechanical energy of this oscillator? Tries 0/99 A 0.450 kg air-track glider is attached to each end of the track by two coil springs. It takes a horizontal force of 0.900 N to displace the glider to a new equilibrium position, x= 0.150 m. 5 0000 00000 -X +X Find the effective spring constant of the system. Submit Answer | Tries 0/99 The glider is now released from rest at x= 0.150 m. Find the maximum x-acceleration of the glider. Submit Answer | Tries 0/99 Find the x-coordinate of the glider at time t= 0.430T, where T is the period of the oscillation. Submit Answer | Tries 0/99 Find the kinetic energy of the glider at x=0.00 m. Submit Answer Tries 0/99A masssorin? sstem oscillates with an amplitude of 3.90 cm. If the spring constant is 220 Mm and the mass is 574 9, determine the mechanical energy of the system. Tries 0/99 Determine the maximum speed of the object. Tries 0/99 Determine the maximum acceleration. Z Tries 0/99
