Q6 \\ B: A person with 99 kg stands on a bathroom spring scale while riding in an elevator. What is the weight indicated on the scale in each of the following cases? The elevator has downward acceleration of g/6 a- 142 Kg b- 74Kg c- 50Kg d- 71KgQ4: Consider the motion of the particle with r = 1, d = wt, 0 = 2 8 cos 4wt where I is constant. By using the spherical coordinates, the speed as a function of time is A. 12w2cos2(cos2w) + 1202-- sin? 2wt B. 12 w2 cos2 ("cosw) -1202--sin2 4wt C. 12w cos2("cos4w) + 12(12 sin2 4wt D. 12w cos (-cos4w) + 12w2-sin2 4wt
