A2.00 kg block hangs from a spring balance calibrated in newtons that is attached to the ceiling of an elevator.(a) what does the balance read when the elevator is ascending with a constant speed of 29 m/s? ? n(b) what does the balance read when the elevator is descending with a constant speed of 25 m/s? ? n(c) what does the balance read when the elevator is ascending at 39 m/s and gaining speed at a rate of 10 m/s2? ? n(d) suppose that from t = 0 to t = 4.9 s, the elevator ascends at a constant speed of 10 m/s. its speed is then steadily reduced to zero during the next 3.2 s, so that it is at rest at t = 8.1 s. describe the reading of the scale during the interval 0 < t < 8.1 s. t0 ? 4.9 = nt4.9 ? 8.1 = n
