5 seconds later B4-BCT15: OBJECT CHANGING VELOCITY WORK AND KINETIC BAR CHART TIPERS A 2 kg object changes its velocity as a force acts on it for 5 seconds. It changes its velocity from 4 m/s cast to 6 m/s cast as shown. Complete the work and kinetic energy bar chart for this process. The bar heights should be in correct proportion to one another.
