A reference is critical because it determines how much motion has occurred. You can't determine how much an objected has moved if you don't know where it came from.
Answer:
F= 403429 kpa
Explanation:
Pressure is the product of force and area
Mathematically,
P=F*A -------where F is force and A is area.
A= 40 *0.1 = 4mm² -----convert to m²
A= 4e⁻⁶ m²
P= 4000000 pa
F= P/A = 4000000/4e⁻⁶
F= 403428793.493 pa
F= 403429 kpa
<span>Cartilage is the hard but flexible structure found in pieces of your nose and ears. It is similar to bone, but allows for flexibility and movement. When looking at skeletons, you'll notice that they don't have a nose or ears, because cartilage deteriorates much faster than bone. Cartilage is also found in elsewhere in the animal kingdom--the skeletal structure of a shark is made primarily from cartilage!</span>
<span>This problem is solved by the equation of motion:
x = x0 + v0*t + 1/2*a*t^2,
Here x0 = 0, v0 = 40ft/sec and a = -5 ft/s^2, we need to solve for t:
v = v0 + a*t, solve how long does it take to stop: 0 = v0 + a*t --> a*t = -v0 --> t = -v0/a
-- > 40/5 = 8 seconds to stop.
In this time, the car travels x = 0 + 40*8 + 0.5*-5*8^2 ft ~ 160 ft.
Answer: The car travels 160 ft.</span>
