Answer: 33.6 m/s

Explanation:

Given

The initial mass of the object is 6\ kg

It breaks into two fragments of 3.5 and 2.5 kg

3.5 kg part moves at 24 m/s towards left

Suppose 2.5 kg part moves with a speed of v towards the right

As the center of mass is at rest before the collision, it continues to remain at rest after the collision.

\therefore 6\times 0=3.5\times 24-2.5\times v\\\Rightarrow 3.5\times 24=2.5\times v\\\\\Rightarrow v=33.6\ m/s

Therefore, the velocity of 2.5 kg mass is 33.6 m/s towards right.

Station 1: Sierra is running in a school track
timofeeve [1]

Answer:

The body systems that work together to maintain the energy Sierra needs are;

The digestive system, the respiratory system, and the circulatory system

Explanation:

Cellular respiration in the body cells require oxygen to produce energy which are used by the muscles and other body cells. Carbon dioxide is also produced and is the build up of carbon dioxide has to be removed from the body as the by product of cellular respiration which is toxic at the cell level

Therefore, the body systems that work together to maintain the energy Sierra needs are;

The digestive system; Takes in the energy containing food and brakes them into chemicals that are transported to the cells for cellular respiration

The respiratory system; Takes in oxygen and removes carbon dioxide from the blood from and to the atmosphere

The circulatory system; Supplies food and oxygen from the digestive and respiratory system to the cells and transports produced carbon dioxide from the cells to the lungs from where it is passed out of the body by th respiratory system.
