Problem

A laboratory device exerts a constant horizontal force of

18.0\pm0.2\,\text{N}

on a glider. The glider’s acceleration is measured to be

0.600\pm0.005\,\text{m/s}^2

. Using proper significant figures, what is the glider’s mass and its absolute uncertainty? a)

(30.0\pm0.6)\,\text{kg}

(29.7\pm0.6)\,\text{kg}

(30.0\pm0.4)\,\text{kg}

(30\pm1)\,\text{kg}
