When a fighter pilot feels massive amounts of force when their planes turn quickly applies to_
sattari [20]

Answer:

The answer is A - Newtons First Law

Explanation:

The law is what we call "Inertia". The law basically states that an object wants to stay where it is. We can see the effect from our cars, albeit with less force. When the car turns right, your body goes left, opposite to the turns direction due to us moving position in the car.

A ship leaves a port at noon and travels due west at 20 knots. At 6 PM, a second ship leaves the same port and travels northwest
Amanda [17]

Answer:

v = 12.44 Knots

Explanation:

First ship starts at Noon with speed 20 Knots towards West

now we know that 2nd ship starts at 6 PM with speed 15 Knots towards North West

so after time "t" of 2nd ship motion the two ships positions are given as

r_1 = 20(t + 6)\hat i

r_2 = 15(t)(cos45\hat i + sin45\hat j)

now we can find the distance between two ships as

x = \sqrt{(20(t + 6) - 10.6 t)^2 + (10.6t)^2}

now we have

x^2 = (120 + 9.4 t)^2 + (10.6 t)^2

x^2 = 200.72 t^2 + 14400 + 2256 t

now we will differentiate it with respect to time

2x\frac{dx}{dt} = 401.44 t + 2256

here we know that

t = \frac{90}{15} = 6 hours

so we have

x = 187.5

now we have

2(187.5) v = 401.44(6) + 2256

v = 12.44 Knots
