What speed does it have when it slides back down to its starting point? 2.8 m/s 4.9 m/s 4.2 m/s 3.5 m/s
Tim got a huge birthday gift from his grandmother. A 400. N crate has been delivered to his driveway. In order to get it started moving toward his door, he has to push it with a horizontal force of 250 N, but as soon as it is moving, he can keep it moving at a constant speed by pushing with a 120 N force. What are the coefficients of static and kinetic friction of Tim's birthday gift and the driveway?
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
