Answer:
d=√[(x₂ - x₁)² + (y₂ - y₁)²]
mass x velocity which equals to ML/T
Answer:
Explained
Explanation:
Given:
Ship travels due east from the Bar Harbor 38 miles before turning north
Yes it possible to calculate the exact direction of the ship by assuming there are no large islands in the way, and that the isolated ship does not cut off very far, then what we have here is a right triangle with a 72-mile as hypotenuse and a 38-mile as "adjacent" side. If θ is the angle out of Bar Harbor, we can write
, and θ = 58.14457°, or 58° 8' 40" north of east. That will be the exact direction.
The distance an object falls, from rest, in gravity is
D = (1/2) (G) (T²)
'T' is the number seconds it falls.
In this problem,
0.92 meter = (1/2) (9.8) (T²)
Divide each side by 4.9 : 0.92 / 4.9 = T²
Take the square root
of each side: √(0.92/4.9) = T
0.433 sec = T
The horizontal speed doesn't make a bit of difference in
how long it takes to reach the floor. BUT ... if you want to
know how far from the table the pencil lands, you can find
that with the horizontal speed.
The pencil is in the air for 0.433 second.
In that time, it travels
(0.433s) x (1.4 m/s) = 0.606 meter
from the edge of the table.
