During the 5 seconds this force acts, the object changesits velocity from 3 m/s east to 7 m/s west.3 m/sA student states:"The change in kinetic energy of this object during these 5 seconds was 40 J, and thus the work doneon this object by the net force during this period was also 40 J."5 seconds later:What, if anything, is wrong with this statement?

Three students discussing this situation make the following contentionsabout the bicycle's kinetic energy:Axel:92-= 2,25m d₂ = 1₂² ₂1x7290 212²6-7.2.2x2"The bicycle is just going to slow down naturally. It doesn't take any work forsomething to slow down."Which, if any, of these students do you agree with?AxelBramCassieNone of themExplain.W=0k€ W²= 1/2mv²_ _/mu²"I disagree. The speed of the bike decreased, so there is a change in kinetic energy.That means work was done on the bike.164"I think Axel is right that no work was done, but I don't agree with his reason. Thereis no work being done here because there are no external forces being exerted."
