You're doing this experiment on Mars, where gravity is only 0.38g (where g is Earth's gravity). You take a sample of MXQ1 with a mass of 23 kg, and place it on a flat surface made of MZX2. You give it a horizontal push of 10 N, and it doesn't move. You increase the force to 20 N, and still nothing. 30 N, still nothing. Finally, when you increase the force all the way to 47 N, the sample starts moving. You keep pushing until it reaches a speed of 5.6 m/s, and then you let go. When you let go, it keeps moving, but slows down, and after 3.4 seconds, it comes to a stop a) What is the coefficient of kinetic friction between MXQ1 and MZX2? b) What is the coefficient of static friction between MXQ1 and MZX2?
