an eagle has a mass of 8 kg and is flying 85 m above the ground with a speed of 20 m/s. what is the total mechanical energy of the eagle?

Answers

Answer 1

Answer: Total Mechanical Energy = KE + PE

KE = (1/2)mv²

= (1/2)*8*20² = 1600 J

PE = mgh g ≈ 10 m/s²

= 8 * 10 * 85 = 6800J

Total Mechanical = 1600 + 6800 = 8400 J.

The Milky Way is located in the _____ Group. Andromeda Local Elliptical Spiral Virgo

Answers

The Milky Way is located in the "local" Group.

The Local Group is the galaxy group that incorporates the Milky Way. The Local Group involves in excess of 54 galaxies, the greater part of them predominate cosmic systems. Its gravitational focus is found somewhere close to the Milky Way and the Andromeda Galaxy. The Local Group has a breadth of 10 Mly (3.1 Mpc) (around 1023 meters) and has a paired (dumbbell) distribution. The gathering itself is a piece of the bigger Virgo Supercluster, which might be a piece of the Laniakea Supercluster.

Final answer:

The Milky Way is located in the Local Group of galaxies and is a spiral galaxy. More than 54 galaxies including Andromeda and the Milky Way are in the group.

Explanation:

The Milky Way is located in the Local Group of galaxies. This group is a collection of more than 54 galaxies, including the Andromeda and Milky Way galaxies, which are the two largest galaxies in the group. The Milky Way is a spiral galaxy, which means it has a flat, spinning disk with a central bulge surrounded by spiral arms. Despite its presence in the Local Group, the Milky Way has no direct connection to the Elliptical or the Virgo groups.

A skater goes down a hill with a constant acceleration of 2.25 m/s2 for 50 meters. If the skater's final velocity was 20 m/s, calculate her initial velocity.

Answers

Answer:

The initial velocity of the skater is 13.22 m/s.

Explanation:

Given that,

Acceleration of the skater, $a=2.25\ m/s^2$

Distance covered, d = 50 m

The skater's final velocity was, v = 20 m/s

We need to find the initial velocity of the skater. It can be calculated using third equation of motion as :

$v^2-u^2=2ad\n\nu=√(v^2-2ad) \n\nu=√((20)^2-2* 2.25* 50) \n\nu=13.22\ m/s$

So, the initial velocity of the skater is 13.22 m/s. Hence, this is the required solution.
