Answer:
Explanation:
Given
mass of climber= 62 kg
velocity of climber before it hits=7.9 m/s at an angle of from vertical
therefore change in momentum in vertical direction is
there is no change in horizontal momentum
and impulse=change in momentum
F.dt=946.22
For non padded floor
Answer:
A runner sprints for 20 minutes at an average pace at 7mph.what is the distance traveled?
Explanation:
140
Irregular Bones
An irregular bone is one that does not have any easily characterized shape and therefore does not fit any other classification. These bones tend to have more complex shapes, like the vertebrae that support the spinal cord and protect it from compressive forces. Many facial bones, particularly the ones containing sinuses, are classified as irregular bones.
Sesamoid Bones
A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. These bones form in tendons (the sheaths of tissue that connect bones to muscles) where a great deal of pressure is generated in a joint. The sesamoid bones protect tendons by helping them overcome compressive forces. Sesamoid bones vary in number and placement from person to person but are typically found in tendons associated with the feet, hands, and knees. The patellae (singular = patella) are the only sesamoid bones found in common with every person. [link] reviews bone classifications with their associated features, functions, and examples.

The mass of an atom comes from the protons and neutrons that is found in the nucleus. The number of protons is the atomic number of an element. To find the number of neutrons, subtract the atomic number from the mass of an atom. For example, sodium’s atomic number is 11. This will tell us that sodium has 11 protons in it. The atomic mass of sodium is 23. So subtract 23 form 11 gives us 12. Therefore, there are 12 neutrons in sodium.
The humerus<span> is the only bone of the upper arm. It is a long, large bone that extends from the scapula of the shoulder to the </span>ulna<span> and radius of the lower arm. The proximal end of the </span>humerus<span>, known as the head, is a round structure that forms the ball of the ball-and-socket shoulder joint.
</span>I just got it from google normaly i would simplify it but its to simple for me to simplify again hope this helps
