You are quite excited with the lesson in friction that you learned in Physics 1A that you decide to measure the coefficient of kinetic friction of surfaces. You try your idea on a glass surface and a glass cup (mass = 0.15 kg). You set the glass cup moving with an initial speed of 2.8 m/s. After travelling a length of 1 m, it stopped. What then is the coefficient of kinetic friction of the glass-glass surfaces? 0.42 0.94 0.56 O 0.15 0.40 O O
