- A car of mass M = 1500 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle 0, and there is no friction between the road and the car's tires as shown in ( Figure 1). Use g = 9.80 m/s² throughout this problem. Figure 1 of 1 Part A What is the radius r of the turn if 0 = 20.0° (assuming the car continues in uniform circular motion around the turn)? Express your answer in meters. ► View Available Hint(s) r = Submit VE ΑΣΦ 20 ? Review | Constants | Periodic Table m2. A bead on a wire can slide with negligible friction on a hoop with radius R rotating at a constant rate with a period T. а. Find the angle 0 at which the bead would not slide on the hoop. Express this in terms of the values given above and any constants (e.g. g). Note: A FBD and proper setup of NII equations are required here. Do your algebra. b. If the period increases, will the bead slide upward, slide downward, or do neither? Explain why, using your result from part a. Can 0 be greater than or equal to 90°? Why or why not? Use FBDS and your result С. from part a as evidence. d. Are there any other angles at which the ball will not slide on the hoop? Explain why. Note: Think very carefully about your forces here. Use FBDS.Please answer question 6 parts a-c

- 9. If a passenger vehicle travels in a circular path at too high a speed, it can tip over. The image below shows a vehicle beginning to tip over. A group of students investigated the speed at which a passenger vehicle will begin to tip over by using a remote- control toy car. The students drove the car around circular paths of various known radii, at such a speed that it was just starting to tip for each radius. They timed the period of the cars motion and used the period to calculate the 'tipping speed' (the speed at which the toy car begins to tip over) of the car. The graph below shows the data collected by the students: Speed at which toy car begins to tip over (m s'¹') 14 12 10 8 TESTO 0 2 3 Radius (m) 5 6 7 Page 11Imagine a meter stick set up as in the figure (in the video above). It hangs from a central bracket, and two hanging masses can hang from it from each of their brackets. At a third location, a force probe can either pull up or pull down on the stick, depending on what is needed to balance the stick. The mass of the meter stick is 120 g. sketch the situation (drawing r1, r2, r3, F1, F2, and F3) and determine the magnitude (value) and direction (+ or -) of each torque. Remember that the x value given in the table is the position of the hanging mass, but that might be different from the r value you need to use. Don't include the mass of a bracket that would hold the hanging mass in place; assume the mass listed is the entire mass hanging at that point.Please answer part d super fast
