The force applied against an object moving horizontally on a linear path is described by #F(x)=2x +2 #. By how much does the object's kinetic energy change as the object moves from # x in [ 1, 3 ]#? Physics Work and Energy Energy 1 Answer Narad T. Apr 6, 2018 The change in kinetic energy is #=12J# Explanation: The change in kinetic energy is equal to the work done. #DeltaKE=W# The work is #W=intFdx=int_1^3(2x+2)dx# #=[x^2+2x]_1^3# #=(9+6)-(1+2)# #=15-3# #=12J# Answer link Related questions How do matter and energy interact?
