Question
assuming the block comes to the rest after a distance of d = 2.70m, what is the coifficient of kinetic friction?
ril 2nd 2018 g on a flat Name flat surface mes t o rest after a dis i friction has with f a distance of d a an initial ve 0.057 0.113 C) 0.124 D) 0.170 2.7 s the coefficient of kinetice fricion? B) E) 0.340 eight h) and stick to a second cart with the same mass m.What ter they stick together? Assume there is no friction in the of mass m is released from rest from the top of a ramp. It sides down avity is g.Explanation / Answer
Solution:
Using the formula , v^2 - u^2 = 2 * a * s ( where a is acceleration and s is distance)
=> (0)^2 - 9 = 2 * a * 2.7
=> a = -1.67 m/s^2
Now Here , m*a = ?*m*g holds
=> a = ? * g
=> ? = a / g
=> ? = 1.67 / 9.81
=> ? = 0.170
