How much power is needed to accelerate an object with a mass of #6 kg# and a velocity of #3 m/s# at a rate of #9 m/s^2#? Physics Work and Energy Power 1 Answer ali ergin Apr 22, 2016 #P=162W# Explanation: #"work is described as "W=F*Delta x# #F:"Force"# #Delta x="displacement of object"# #"we can write F=m*a"# #W=m*a* Delta x# #Power=P=W/(Delta t)# #P=(m*a*Delta x)/(Delta t)# #(Delta x)/(Delta t)=v" velocity"# #P=m*a*v# #m=6 kg" "a=9m/s^2" "v=3 m/s# #P=6*9*3# #P=162W# Answer link Related questions What is power?
