Assume you are on a planet similar to Earthwhere the acceleration of gravity is approxi-mately 10 m/s2 and the positive directions fordisplacement, velocity, and acceleration areupward.At time t = 0 s, an elevator is at a displace-ment of x = 0 m with a velocity of v = 0 m/s.A student whose normal weight is 400 Nfilipkowska (kf6839) – Chapter 4 Quiz – wollins – (1954) 3stands on a scale in an elevator and recordsthe scale reading as a function of time. Thedata are shown in the graph.02004006008000 5 10 15 20time (s)Scale Reading (N)In which direction does the force due to thescale act on the student?
