A 4500 kg vehicle and a 3700kg vehicle are both moving at a speed of 85m/s toward east.Calculate the momentum of each veheicle?
lana [24]
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

Isolating a variable in two equations is easiest when one of them has a coefficient 1.
Tomtit [17]

Answer:

Option C.

Step-by-step explanation:

The given equations are

3A-B=5

2A+3B=-4

We need  isolate one of the variables, such that it appears by itself on one side of the equation.

Isolating a variable in two equations is easiest when one of them has a coefficient 1.

In equation 1, coefficient of B is 1. So, we can easily isolate one of the variables.

The equation is

3A-B=5

Subtract 3A from both sides.

-B=5-3A

Multiply both sides by -1.

B=3A-5

Therefore, the correct option is C.
