1. The problem statement, all variables and given/known data An electric motor is used to pull a 125 kg box across a floor using a long cable. The tension in the cable is 350N and the box accelerates at 1.2m/s2 (forward) for 5.0s. The cable breaks and the box slows down and stops. Calculating the coefficient of kinetic force? Given: m=125 kg a= 1.2 m/s2 t= 5.0s Ft=350 N 2. Relevant equations uk=Fk / FN 3. The attempt at a solution Fnet = ma Fnet = (125kg)(1.2m/s2) Fnet = 150 Thought Fk would be 350N because that's the Ft. And then Uk would equal 350N divided by 150 but I got 2.3 when the answer is 0.16 not sure how to get answer?
