Answer:
V=27.24 m/s
Explanation:
We need to apply the linear momentum conservation theorem:
The velocity of the eagle its defined by its two components:
because speed is a scalar value:
Answer:
Whats the question/word problem or where is the graph (if included) representing this problem?
Find the amount of work that the spring does. This can be found using the equation 1/2kx^2. Then, you must set that equal to the amount of kinetic energy the car has. This is possible thanks to the work-energy theorem.
1/2kx^2 = 1/2mv^2
Solve to find velocity. Remember, the spring is displaced .15 m, not 15!
To find the acceleration, use F = ma. The force being applied to the car is kx, and you know the mass. You do the math.
For problem C I don't know, haven't done that yet in my class. Sorry!
answer:
a.fossils of the same plants and animals are found on widely spread continents
explanation:
four fossil examples include; the mesosaurus, cynognathus, lystrosaurus, and glossopteris.
good luck :)
i hope this helps
have a nice day !!
