1.A 55 KG bungee jumper leaps from a bridge. She is tied to a bungee cord that is 12 m long when unstretched, and falls a total of 31 m. Calculate the spring constant of the bungee cord assuming Hooke's law applies. Calculate the maximum acceleration she experiences
2.The uniform bar has a mass m and length l. if it is released from rest when theta = 0 degrees, deterine its angular velocity as a function of the angle theta before it slips
