A 0.500 kg glider on an air track is attached to the end of an ideal spring with force constant 455 N/m; it undergoes simple harmonic motion with an amplitude of 4.90×10-2m.
1. Calculate the max speed of the glider Vmax=____m/s
2. Calculate the speed of the glider when x=-1.0*10^-2 m, v=___m/s
3. Calculate the magnitude of the maximum acceleration of the glider. a max=____m/s2
