If an object is moving at #6 m/s# over a surface with a kinetic friction coefficient of #u_k=3 /g#, how far will the object continue to move? Physics Forces and Newton's Laws Frictional Forces 1 Answer ali ergin Feb 5, 2016 #x=6 m# Explanation: #Delta E_k=1/2 .m. (v^2-0^2)# #Delta E_k=1/2 .m. v²# #"work doing by friction force=W"# #W=Delta E_k# #u_k . m. g. x=1/2 .m .v^2# #3/cancel(g) .cancel(m) .cancel( g) . x=1/2 .cancel(m).6^2# #6.x=36# #x=36/6# #x=6 m# Answer link Related questions Question #d6539 Question #242b7 Question #6bde4 Question #50c79 Question #a2018 Question #f7a62 Question #27931 Question #0b375 Question #d70af Question #dab6f See all questions in Frictional Forces Impact of this question 1293 views around the world You can reuse this answer Creative Commons License
