College Physics: Reasoning and Relationships

Figure 2.24 shows one of Galileo's experiments in which a ball rolls up an incline. A ball that is initially rolling up the incline will roll up to some maximum height and then roll back down the incline. Draw qualitative plots of the position and velocity as functions of time for the ball. Take $x=0$ at the bottom of the ramp.

College Physics: Reasoning and Relationships

A block is sliding at a particular initial speed $v$ when it encounters the following horizontal surfaces:
a. a grass field,
b. an asphalt street,
c.a hardwood floor,
d. an ice rink (with real, not ideal, ice), and
e. an ideal, friction less surface.
Draw qualitative plots of the velocity as a function of time for each case, with $t=0$ corresponding to the time at which the block reaches each of these surfaces.

College Physics: Reasoning and Relationships

A flatbed truck hauls a block of ice on top of which stands a penguin (see Fig. P2.40). Assume the block of ice is frozen solid to the bed of the truck, but the top surface of the ice is extremely slippery. The truck skids to a stop from an initial velocity of $20 \mathrm{m} / \mathrm{s}$. Describe what happens to the penguin in terms of Newton's first law. How does it differ from what happens to the driver of the truck, who is wearing a seat belt? Draw and compare the velocity-time graphs of the penguin and truck driver.

A flatbed railcar is moving at a slow but constant velocity. A man stands in the railcar, facing sideways (perpendicular) to the motion of the railcar. The man holds a baseball at arm's length and drops it onto the railcar bed. Where does the principle of inertia predict that the ball will land:
a. directly below the drop point on the railcar,
b. slightly in front of the drop point on the railcar, or
c. slightly behind the drop point on the railcar? Explain.

College Physics: Reasoning and Relationships

Consider a skydiver who jumps from an airplane. Suppose she waits for 1 min before opening her parachute and she lands 4 min after leaving the airplane. Draw qualitative plots of the position, velocity, and acceleration as functions of time for the skydiver, starting from the time she jumps from the plane, assuming (somewhat unrealistically) that she falls straight down. Here, the position $y$ is her vertical height above the ground. Be sure to indicate the time at which she opens the parachute. Hint: Consider how the velocity will vary with time after the chute is open for a long time.
