Answer:
<h2>64.4 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
mass = 9.2 kg
acceleration = 7 m/s²
We have
force = 9.2 × 7 = 64.4
We have the final answer as
<h3>64.4 N</h3>

28.65m x 15.24m
Explanation:
The size of a basketball court in the NBA is usually 28.65m x 15.24m giving a total court area of 436.62m².
The NBA is the acronym for National Basketball Association. It comprises of several teams from across United states and Canada in basketball league.
- The game is played by hand with a target basket.
- For each successive throw into the basket, 1 or 2 or 3 points can be awarded.
- In feets the dimensions are 94 by 50 feet
- From the dimension we can accurately say that a basketball court is rectangular in shape.
- James Naismith is credited with the invention of the game of basketball

Answer:
Part(a): The value of the spring constant is
.
Part(b): The work done by the variable force that stretches the collagen is
.
Explanation:
Part(a):
If '
' be the force constant and if due the application of a force '
' on the collagen '
' be it's increase in length, then from Hook's law

Also, Young's modulus of a material is given by

where '
' is the area of the material and '
' is the length.
Comparing equation (
) and (
) we can write

Here, we have to consider only the circular surface of the collagen as force is applied only perpendicular to this surface.
Substituting the given values in equation (
), we have

Part(b):
We know the amount of work done (
) on the collagen is stored as a potential energy (
) within it. Now, the amount of work done by the variable force that stretches the collagen can be written as

Substituting all the values, we can write
