Vectors: A boat moves through the ocean on a foggy day. The boat is pointing North and can typically move at a speed of 12.8 m/s

in calm waters. The boat travels through water where there is a 5.9 m/s current flowing to the East. What is the speed of the boat relative to a stationary observer on land? __m/s Part 2 The boat turns to face directly West. Now how fast is the boat moving relative to land? __m/s

Answer:

1.) 14.09 m/s

2.) 6.9 m/s

Step-by-step explanation:

Given that the boat is pointing North and can typically move at a speed of 12.8 m/s in calm waters. The boat travels through water where there is a 5.9 m/s current flowing to the East.

The speed of the boat relative to a stationary observer on land will be achieved by using pythagorean theorem

V^2 = 12.8^2 + 5.9^2

V^2 = 198.65

Square root both sides

V = 14.09 m/s

2.) If the boat turns to face directly West.

Since the boat can move at speed 12.8 m/s in a calm water, the speed of the boat if it face west will be

12.8 - 5.9 = 6.9 m/s

Therefore, the boat is moving relative to land at 6.9m/s

Answer:

\huge\boxed{\text{(A) 2 units left and 4 units up}}

Step-by-step explanation:

You were right!

If we want to transform figure ABCD onto figure A'B'C'D', we need to note that no dilation/rotation/reflection is needed. They're just units apart.

Let's focus on a specific point, as when we move that the whole figure will too.

Let's do B/B'.

We can see that in figure ABCD, point B is at (1, -1). On A'B'C'D', point B' is at (-1, 3).

Lets first change the x values.

What we need to ask is - what's the distance from 1 to -1? We know that from 1 to 0 is 1 point and from 0 to -1 is another 1 point. So, 1+1 = 2. It's a 2 point difference to a smaller number. So we move left.

Same logic applies for y values. What's the difference from -1 to 3? From -1 to 0 is 1 unit, and from 0 to 3 is 3 units. So, the difference is 4 units upwards.

So, 2 units left and 4 units up.

Hope this helped!
