3. A 200g air glider is set up to move with almost no friction on a track. It has springs attached to both ends which give the system a combined spring constant of 30 N/m. At time t = 0, the glider has a velocity of 1.5 m/s 2 and is located at the equilibrium position. For this system, find the amplitude, period, angular frequency, and total energy, and write an equation of motion for the system. 4. A simple pendulum is made by hanging a 0.30 kg mass on a string so that the distance from the pivot to the center of the mass is 0.30 m. (a) What will the period of this pendulum be? (b) If the pendulum is pulled back to an angle of 10°, what will the horizontal velocity of the mass be when it reaches the bottom of its swing? (c) What is the tension in the string when the mass reaches the bottom of its swing?
