Example 11-9 depicts the following scenario. a cat walks along a plank with mass m= 7.00 kg. the plank is supported by two sawhorses. the center of mass of the plank is a distance d1= 0.850 m to the left of sawhorse b.
when the cat is a distance d2= 1.11 m to the right of sawhorse b, the plank just begins to tip?

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
