Three masses {m3 = 6.0 kg ; m2 = 4.0 kg; m1 = 9.0 kg] are connected as shown. with a massless and frictionless pulley. If the coefficient of kinetic friction is 0.100, calculate the tension between the two masses on the inclined plane {elevated at 30 degrees above the horizon]. Assume the system begins to move. A boat is able to move at 16 ms in still water. If the boat is placed on the south shore of a river [water current of 3.4 mfs [SE]}. and the captain wants to head straight across to the north shore: a] In what direction should the captain point the boat? [3 marks] h] Calculate the time it will take to cross {the river is 212.0 rn from the south to the north shore]. [2 marks] \fA high school phvsics teacher designs an activity for her students to explore uniform circular motion in a vertical circle. She buvs a rigid plastic rod, advertised of having a tensile strength of 34.0 N, and uses a rubber stepper of mass 19.6 g. If the radius of the circle the students will use is 1.45 rn, calculate the highest frequency of oscillation the students can use and not have the string break. (Hint: Think where the max tension would be]
