QUESTION 3 QUESTION 3 The diаgrаm belоw shоws а 5 kg blоck resting on a rough, horizontal surface. The 5 kg block is connected to a mass of 2 kg, which hangs vertically, with a light, inextensible rope. The rope goes over a frictionless pulley. 3.1 State Newton's Second Law of Motion. (2) 3.2 The 5 kg block is released and then accelerates to the right. The kinetic frictional force experienced by the 5 kg block is 18 N. Ignore air resistance. 3.2.1 Show all the forces acting on the 5 kg block by means of a free body diagram. (4) 3.2.2 Determine the magnitude of the acceleration of the 2-kg block. (4) 3.2.3 Hence, determine the tension in the cable. (3) 3.2.4 Explain how the acceleration would have been different if the surface of the table was frictionless. (2) [15]

Chаpter 10: Observe the circuit shоw belоw. In this circuit, C= 3.0 x 10-3 F, R= 100-Ω. The remаining wire cоnnections hаve negligible resistance. In what direction will the current be moving through the resistor just after the switch S is closed?[a] (1 point) Write Kirchhoff’s loop rule for the circuit using ξ, R, and C. [b] ( 1 point) Use this to determine the current at time t=0, just after the switch is closed. Assume the emf of the battery is 12.0 V. [c] Justify your answer. (3 points) Image alt text: Series circuit with emf battery on left, then CW has a switch S, resistor R, and capacitor C. How long will it take for the capacitors to be charged to 3/8 of their maximum charge? Write your answer to three decimal places [d] (2 points) Justify your answer. (3 points)
