Answer:
Displacement CO=2.15 Km
Average velocity = 1.99 Km/h
Explanation:
Given
Total time = 1.08 h
OA= 1.62 Km
AB=0.246 Km
BC=3.08 Km
θ=50.4°
CE=3.08 sin50.4° =2.37 Km
BE=3.08 cos50.4° =1.96 Km
CE=AB+OD
OD=CE-AB
OD=2.37-0.246
OD=2.124 Km
BE=CD+OA
CD=BE-OA
CD=1.96-1.62
CD=0.34 Km
Now CO
CO=2.15 Km
So the displacement CO=2.15 Km
Average velocity =Displacement/Time
Average velocity = 2.15/1.08 Km/h
Average velocity = 1.99 Km/h
Answer:
Velocity = 4.85m/s

Answer: a) The Answer to the question is option a) None of it.
Explanation:
The reason is because according to the law of conservation of energy Energy can neither be created nor destroyed but can be transformed from one form to the other. Therefore none of the kinetic energy was dissipated, rather it was transformed to another form of energy.
