Question

How much work is done (in J) when a weight lifter lifts 190 kg from 1.5 m to 2.0 m above the ground? (Use 9.8 m/s2 for g.)

Expert Solution
Step 1

Given data:

  • Mass, m=m=190 kg
  • Initial height, h1=1.5 m
  • Final height, h2=2 m
  • Acceleration due to gravity, g=9.8 m/s2

Our question is to find the amount of work done.
