The obd-ii catalytic converter monitor uses sensor(s) to monitor catalytic converter efficiency. a. front and rear catalyst temperature b. a throttle position c. front and rear o2 d. an engine coolant temperature

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
