Answer:
Part a)
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part b)
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part c)
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Explanation:
Red car
mass = 1000 kg
speed = 10 m/s
Yellow car
mass = 2000 kg
speed = 5 m/s
Blue car
mass = 500 kg
speed = 20 m/s
Light Blue car
mass = 1000 kg
speed = 20 m/s
Green car
mass = 500 kg
speed = 10 m/s
Purple car
mass = 4000 kg
speed = 5 m/s
Part a)
Now we know that momentum of each car is product of mass and velocity
so we will have
Red Car
Yellow Car
Blue Car
Light Blue Car
Green Car
Purple Car
So the momentum is given as
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part b)
Impulse is given as change in momentum so here we can say that final momentum of all the cars will be zero as they all stops and hence the impulse is same as initial momentum of the car
so the order of impulse from largest to least is given as
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part c)
Force is defined as rate of change in momentum
Now let say all cars will stop in same time interval
so we will have
so we will have
force is in same order as that of impulse
so it is given as
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
