SOLUTION: A box is given a push so that it slides across the floor. Given that the coefficient of kinetic friction is 0.15 and the push imparts an initial speed of 3.5 m/s. Determine how far

Question 1161490: A box is given a push so that it slides across the floor. Given that the coefficient of kinetic friction is 0.15 and the push imparts an initial speed of 3.5 m/s. Determine how far it will go.

The law of energy conservation says that the initial kinetic energy is equal to the work of the friction  force


     = k*m*g*x


Cancel the common factor "m" (the mass) in both sides. Then substitute the given data and find the the length x 
"how far it will go".

     = 0.15*9.81*x

    x =  = 4.16 meters.    ANSWER

Solved.
