Vmax
In a laboratory experiment, a sphere of diameter
8.0 mm is released from rest at t = 0 at the surface of
honey in a jar, and the sphere's downward speed v
when it travels in the honey is found to be given by
v = Vmax (1 - e-t/T), where
0.040 m/s and
T = 0.50 s. (a) Obtain an expression for a(t). (b) Draw
graphs for v(t) and a(t) for the time interval 0 to 2.0 s.
(c) Obtain an expression for x(t), choosing the positive
x axis as downward, and draw the graph for this func-
tion. (d) Use your x(t) graph to determine the time
interval needed for the sphere to reach the bottom of the
container if the surface of the honey is 0.10 m above the
bottom of the jar. ...

34. On a freeway entrance ramp, you accelerate your
1200-kg car from 5 m/s to 20 m/s over 500 m. Having
an open lane, you continue to accelerate at the same
(constant) rate for another 500 m. Is your final speed
35 m/s, less than 35 m/s, or greater than 35 m/s?.

9. A 100 kg man gets in an elevator on the 10th floor. He stands still on a scale, which is placed on the floor of the elevator, before the doors close, and the scale reads a value equal to his weight (the largest force of gravity on him). The doors close, and the elevator starts moving downward toward the 1st floor. The elevator speeds up until it reaches the 8th floor, at which point the elevator travels at a constant velocity, which it maintains until it reaches the 3rd floor, at which point it starts slowing down at a constant rate and stops by the time it reaches the 1st floor.
