8. (a) Two springs A and B are attached to a trolley as shown in Fig. 15. Initially, both springs are unstretched. Spring A has a force constant of KA = 25 N/m and spring B has a force constant of kg = 50 N/m. The mass of the trolley is 250 g. support trolley mime min Figure 16 support Figure 15 A student moves the trolley so that Spring B is stretched by 6.5cm. As a result, Spring A is compressed by 6.5cm as shown in Fig. 16. The trolley is then let go. B momt table Find the initial acceleration of the trolley. (b) Assuming the surface on which the trolley moves is frictionless, what is the maximum speed of the trolley during its motion? (c) Is this arrangement of springs similar to a series arrangement or parallel arrangement of springs? Explain. 8. (a) Two springs A and B are attached to a trolley as shown in Fig. 15.
