Giordano: CP 2e ISM, Vol 11CH022 Motion, Forces, and Newton's LawsCONCEPT CHECK2.1I Force and MotionThe motion in (a) is inconsistent with Aristotle's Test bank and solution manual of college physics (2)s law of motion, Equation 2.1, since the puck slides without any force propelling it in the direction of its velocity, and (b) is inconsistent with Equation 2.1 for the same reason. The motion in (c) does appear to be consistent with Aristotle's lav; of motion because a piano will generally stop mov Test bank and solution manual of college physics (2)ing as soon as the force is removed.2.2I Estimating the Instantaneous VelocityYes, there is a value of t at which the velocity is zero in Figure 2.9.Test bank and solution manual of college physics (2)
The instantaneous velocity is equal to the slope of the X - t graph, and this slope is zero at t « 1.6 s in Figure 2.9.2.3I The Relation between VelocGiordano: CP 2e ISM, Vol 11CH022 Motion, Forces, and Newton's LawsCONCEPT CHECK2.1I Force and MotionThe motion in (a) is inconsistent with Aristotle's Test bank and solution manual of college physics (2)city decrease with time for graph 2.(c)The slope and velocity are constant (do not change with time) for graph 1.2.4I Analyzing a Position-Time GraphThe correct answers are (b) and (d) . To understand the motion described by an X - t graph, consider the behavior of the velocity as found from the slo Test bank and solution manual of college physics (2)pe of the X - t plot. In Figure 2.18, this slope-and therefore the velocity-are largest at early times and fall to zero at the end of the motion. HencTest bank and solution manual of college physics (2)

Hence, the forces in (a) are not an action-reaction pair because the pitcher does Test bank and solution manual of college physics (2) not act directly on the bat. For the same reason, the forces in (c) are not an action-reaction pair. The forces in (b) are an actionreaction pair becTest bank and solution manual of college physics (2)

However, the acceleration is always negative (pointing toward the planet), so the velocity will diminish, but never reachzero.Q2.2 Graphs for parts (a) and (b) are sketched below:Giordano: CP 2e ISM, Vol 13CH02Test bank and solution manual of college physics (2)
