Question About Assignment -- accelerations, velocities and distances
Q1.
Q1.What will be the distance traveled by each buses since t=0s?
Q2. Explain how it is possible for
1.a body to undergo acceleration even though it is momentarily at rest
2.a body to undergo acceleration when it is moving with constant speed
3.a body to undergo deceleration when its speed increase
Q3: why is paraffin wax, which has a high concentration of protons, a good absorber of high speed neutrons?
Q1:From my understanding, when t=0 there is no movement so distance = 0
by extending the graph, which the line will be touched the x-axis(x intercept) it's not possible to have negative time.
Q2:Sorry for bad English Understanding(From my understanding, the sentence how it is possible for means that these cases are true but with certain condition then it will occur.
1:external force - gravitational forces OR the surrounding environment is moving(eg Aeroplane?)
2:external force - gravitational forces
3:Frictional force
Q3:Never encounter these before, maybe paraffin wax have high concentration of protons whenever the radiation hit it it could produce high speed neutrons ?? kind ar blurr
