A 0.480-kg pendulum bob passes through the lowest part of its path at a speed of 3.49 m/s.   (a) What is the magnitude of the tension in the pendulum cable at this point if the pendulum is 72.0 cm long?  N (b) When the pendulum reaches its highest point, what angle does the cable make with the vertical? (Enter your answer to at least one decimal place.)  ° (c) What is the magnitude of the tension in the pendulum cable when the pendulum reaches its highest point?

Item 5 In this version of the "Giant Swing", the seat is connected to two cables, one of which is horizontal (Figure 1). The seat swings in a horizontal circle at a rate of 26.0 rpm (rev/min).

Masses m₂, m₂, m3 and om are connected together as shown in the figure below. All the surfaces are smooth. If m₁ = 3.2kg, m₂ = 2.8kg, m3 = 3.8kg, om = 1.3kg and = 55°, calculate a) the acceleration of the system. b) the normal force between m3 and ōm. 7²1 7122 In+one 183
