Aturntable spins up from rest with an angular acceleration of 1.0 rad/s2. a rubber eraser of mass 20 g with coefficientof static friction 1.0 is at a distance of 0.1 m from the center of the turntable, when it begins to spin. how long does ittake for the eraser to begin to slide off the turntable? note that the tangential acceleration of the eraser is very small.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
