Chapter 5, Problem 65GP
CE Each of the three identical hockey pucks shown in Figure 5-44 is acted on by a 3-N force. Puck A moves with a speed of 7 m/s in a direction opposite to the force, puck B is instantaneously at rest; puck C moves with a speed of 7 m/s at right angles to the force. Rank the three pucks in order of the magnitude of their acceleration, starting with the smallest Indicate ties with an equal sign.

at 20 m/s to the left. If vehicles crash and become entangled, determine the distance the vehicles
will slide before they stop. The coefficient of kinetic friction between vehicles' tire and the road
is μι-0.7.
