u -Ms. Vulcan has a mass of 50 kg and Mr. X. weighs 187 lbs. Together they hang from a bungee cord of stiffness 75 N/m. a) If they are at rest and at the equilibrium position then determine how much the bungee cord has been stretched. b) If they currently have an instantaneous acceleration of 0.5 g's upwards, then what is the current stretch of the bungee cord? c) If they currently have an instantaneous acceleration of 0.1 g's downwards, then what is the current stretch of the bungee cord? - Mr Orion sets up the following apparatus with blocks and strings. What are the tensions in string A and string B if the block has a mass of 10 kg and currently stationary and in equilibrium. Remember A and B have vector components! Solve by making two equations with two unknowns. 450 30 String A String B 10 kg 6 - Ms Sagittarius sets up the following apparatus with blocks and strings. What is the coefficient of static friction between 10 kg block and the table surface if the system at rest and in equilibrium where acceleration is zero and nothing is currently moving? Remember string B has vector components. 450 1350 String A String B 10 kg block 5 kg block u
