Daniel takes his two dogs, pauli the pointer and newton the newfoundland, out to a field and lets them loose to exercise. both dogs sprint away in different directions while daniel stands still. from daniel's point of view, newton runs due north at 3.90 m/s, but from pauli's point of view, newton appears to be moving at 1.10 m/s due east. what is pauli's velocity relative to daniel, ⃗ pd?

4.05 m/s

Explanation:

We shall represent the different velocity in vector form

Newton runs due north at 3.90 m/s, with respect to standing Daniel .

V_n = 3.9 j

Let Pauli runs with respect to standing Daniel with velocity X .

Then relative velocity of Newton with respect to running Pauli will be

3.9 j - X

Give that

relative velocity of Newton with respect to running Pauli = 1.1 i ( 1.1 due east )

So

3.9 j - X = 1.1 i

X =  -1.1 i + 3.9 j .

Magnitude of X

X² = 1.1 ² + 3.9²

X = 4.05 m/s

So Pauli runs with respect to standing Daniel with velocity 4.05 m /s .

Direction will be ,  west of north at angle θ ,

Tan θ = 1.1 / 3.9

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
