Answer:
x = 24
Step-by-step explanation:
x/9 = 40/15
x/9 = 8/3
x/9 = 24/9
x = 24
Tan (180 - 45)
- tan 45
-1 is the answer
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
