At this point in the story, Beasy has driven his car (2+6+4) = 12 km.
He is parked at the thrift store, (2+4) = 6 km East and 6 km North of his starting point.
As the crow flies, the thrift store is √(6km² + 6km²) in a straight line from the starting point.
That's √(72 km²) , which works out to 8.485 km . When rounded to the nearest whole km, he can phone up his wife and tell her he's "eight kilometers from home can you hear me now ?".
Displacement is a vector, so to answer the question completely, we also need to state its direction.
The angle from home to the thrift store, relative to East, is arctan(6km/6km).
That's 45 degrees.
The full displacement vector is <em>8.485 km Northeast.</em>
The eagle momentum : 320 kg.m/s
<h3>Further explanation</h3>
Given
mass = 32 kg
d = 100 m
t = 10 s
Required
The momentum
Solution
The velocity of the eagle :
The momentum (P) :
The work done on the spring is equal to the elastic potential energy of a spring. We look at Hooke's law, which states that the force needed to stretch a spring is proportional<span> to the displacement of the spring.
</span><span>F = -kx
W = (integral) Fdx
</span>W = (integral) -kx dx
W = kΔx²/2
20 = k(42 - 30) / 2
k = 10/3
Answer:
the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.
Explanation:
it is the definition
C
Because no matter an objects mass all objects have a gravitational force
