An object glides on a horizontal tabletop with a coefficient of kinetic friction of 0.3 If it comes to rest after 1.3 seconds what was its initial velocity?
Correct and easier way: Kinetic friction is just a part of magnitude of forces affecting an object, so it can be multiplied by g(9.81) to get the total acceleration essentially. Coefficient(.3)=F(friction)/F(normal) So multiply .3 by g(9.81) to get 2.943 -2.943 is the acceleration of the object, as it's slowing down) So then, simply multiply by time (1.3) to get a Vi of 3.8259 Ffriction = -0.3 * m * g = m * a a = -0.3 * g So if we integrate over time: v(t) = -0.3 * g * t + v(0) We know that v(t=1.3) = 0. So we can place it in the equation. v(t=1.3) = 0 = -0.3 * g * 1.3 + v(0) v(t=0) = 0.3*1.3*g = 0.39 * g = 0.507 meters per second
