Not completely understanding what the question is
Answer:
A. 1 in³ / 16.4 cm³
Explanation:
Inches is an imperial unit while centimeter is a metric unit.
1 inch = 2.54 cm
⇒1 inch³ = 2.54³
⇒1 inch³ = 2.54×2.54×2.54
⇒1 inch³ = 16.38 cm³ = 16.38 cc
So,
So, 1 in³ / 16.4 cm³ conversion factor should be used.
Answer:
The velocity is
Explanation:
From the question we are told that
The speed of the roller coaster at ground level is
Generally we can define the roller coaster speed at ground level using the an equation of motion as
u is zero given that the roller coaster started from rest
So
So
=>
Now the displacement half way is mathematically represented as
So
Where is the velocity at the half way point
=>
=>
