Four resistors are connected to a battery as shown in the figure. The current through the battery is I , the battery's electromotive force (emf) is E = 11.45 V , and the resistor values are R 1 = R , R 2 = 2 R , R 3 = 4 R , and R 4 = 3 R . Find the voltages across each resistor.

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.
