Answer» ss = 250 gFinal velocity = 5 m/sInitial velocity = 2 m/s To FindWork DONE SOLUTION:We know that, Work Energy TheoremHere,W = work doneΔ K.E = CHANGE in kinetic energyWe know that,HENCE,According to the question,We are asked to find the work doneSo, we must find "W"Given that,Mass = 250 gFinal velocity = 5 m/sInitial velocity = 2 m/sHence,m = 250 g = 0.25 kgv = 5 m/su = 2 m/sSubstituting the values,We get,On further simplification,We get, |
