The airplane's speed relative to the ground is
√ (100² + 25²)
= √ (10,000 + 625)
= √ 10,625
= 103.08 km/hr .
The angle of its velocity north of west is
the angle whose tangent is (25/100)
arctan(25/100) = 14° north of west .
(bearing = 284°)
All the planets is the answer
We have the relation
where denotes the velocity of a body A relative to another body B; here I use B for boat, E for Earth, and R for river.
We're given speeds
Let's assume the river flows South-to-North, so that
and let be the angle made by the boat relative to East (i.e. -90° corresponds to due South, 0° to due East, and +90° to due North), so that
Then the velocity of the boat relative to the Earth is
The crossing is 153.0 m wide, so that for some time we have
which is minimized when so the crossing takes the minimum 30.0 s when the boat is pointing due East.
It follows that
The boat's position at time is
so that after 30.0 s, the boat's final position on the other side of the river is
and the boat would have traveled a total distance of
Answer:
W = 1.44 10⁻⁷ J
Explanation:
The expression for the job is
W = ∫ F. dx
Where the point is the scalar product in this case the direction of the meteor and the depth is parallel, whereby the scalar product is reduced to the ordinary product
W = 630 ∫ x³ dx
W = 630 x⁴ / 4
Let's evaluate between the lower limit x = 0, w = 0 to the upper limite the point at x = 5.5 10⁻³ m
W = 157.5 ((5.5 10⁻³)⁴ -0)
W = 1.44 10⁻⁷ J
Answer:
Explanation:
The Anti-Federalists had a strong distrust of government power. A national government with too much power was, as far as they were concerned, a pathway to government oppression. In 1787, for example, “Brutus,” who was probably New York judge Robert Yates, wrote to the citizens of New York, “when the people once part with power, they can seldom or never resume it again but by force.”1
