How much work does it take to raise a #9 kg # weight #9 m #? Physics Work and Energy Work 2 Answers Jane Mar 6, 2018 Answer: #793.8 J# Explanation: Here work will be done against the gravitational force,which supplies the required amount of potential energy for the weight to be #9m# above the ground. So,work done=#mgh=9*9.8*9=793.8 J# Junaid Mirza Mar 7, 2018 Answer: #"793.8 Joule"# Explanation: #"Work = Change in Potential energy"# #W = U_f - U_i# #W = "mgh"_f - "mgh"_i# #W = "mg"(h_f - h_i)# #W = "9 kg" × "9.8 m/s"^2 × ("9 m" - "0 m")# #W = "793.8 Joule"# Related questions What is a force?
