Question

8. Michele has a mass of 50 kg and is standing on a force plate in a moving elevator. She finds that her apparent weight is 450 N. Take $g = 10 \text{ m/s}^2$. Draw a FBD for Michele. No double subscripts. Include a coordinate system. a. Find the magnitude of Michele's acceleration: $a = \underline{\qquad} \text{ m/s}^2$ b. The direction of Michele's acceleration is (i) none, $a=0$ (ii) down (iii) up (iv) cannot be determined without further information If you chose (iv), briefly explain: c. Is Michele speeding up, slowing down, neither, or can you not tell? (i) speeding up (ii) slowing down (iii) constant speed (iv) cannot be determined without further information If you chose (iv), briefly explain:
