Answer:
x2-12x+3
Step-by-step explanation:
=x(x-3)-9(x-3)
=x2-3x-9x+3
=x2-12x+3
The momentum formula is
p = m*v
where,
p = momentum (not sure why p is chosen but many physics books tend to pick this letter)
m = mass in kilograms
v = velocity in meters per second
So let's calculate the momentum for the 4500 kg vehicle
p = m*v
p = 4500*85
p = 382500 kg m/s
And let's do the same for the 3700 kg vehicle
p = m*v
p = 3700*85
p = 314500 kg m/s
