Question

s traveling around a direudla rotary wthich has ra ot 100m certain intant of tme, the car is traveing at asperd n at a rate of 1.00 t h of the following diagrams shows the approsimate direction of the car's loweraln a) b) e) d) 9. The centripetal acceleration of the tar has a magnitude of 181m-2. b. 9.80 m a. c. 129 120". Cosio m e. 10 m 10. The overal acceleration of the car has a magnitude df al81%、 b.osiomr2- し29 ms2 d.980 mes, d 980 me THE FOLLOWING PROBLEM IS ENTIRELY SEPARATE AND UNRELATED TO THE ONE ABOVE Donald toasts macadamia nuts in his microwave oven. in the following, consider one such nut nside the mirowave aven, the macadamia nut travels at a constant speed of 2 50 em/s on a circle having a radlus of 5.00 em. 11. Inue or False: The macadamia nut's velocity is chenging with time Trueb. False 250cms 12. The centripetal acceleration of the macadamia nut has a magnitude of a zero b. 0500 m 125 d 980 m e. 0800 cm 13. The tangential acceleration of the macadamia nut has a magnitude of b. 0500 cm c. 980 m 2e. 0800 cm 14. Which of the following diagrams shows the approximate direction of the macadamia nut's (overall acceleration? a) d) e) The macadamia nut is not accelerating, and zero acceleration has no direction. hinge Tungente locity will have 3c rechen

For #13 how is Tangential acceleration 0 can you solve it please. ( what does V2-V1 equal)
For # 8 why is E correct
please give detailed explanation.
