Question

Kody slides a cone on ice with a force of 15 N. What is the mass of the cone if the acceleration of the cone is 1.2 m/s/s and the coefficient between the cone and the ice is 0.18?

Answer 1

$F=15N, \mu = 0.18, a=1.2ms^{-2}, m= ?$

$F= \mu ma$

$15 = 0.18 \times m\times1.2$

$15=0.216m$

$m= \frac{15}{0.216}=69.44Kg$
