ANSWER:
ANSWER: Your mass is 60 kg, Initial velocity u = 0.70 m/s, Final velocity v = 0.70 m/s Distance travelled through the moving sidewalk is 25 meters horizontally. a) The work-energy theorem tells us that, the work done on a system is the difference between initial and final kinetic energy. Mathematically, So, let’s calculate the difference in kinetic energy. The initial K.E was, 1/2 ×(60 kg×0.70 ) = 14.7 jules Final kinetic energy is, 2 1/2 ×(60 kg×0.70
