Answer:
Step-by-step explanation:
Let the speed of the roller coaster at the bottom is v.
radius, r = 47 m
Let the mass is m and the force at the bottom is 2.5 times the weight.
F = 2.5 mg
So, the force is
v² = 1.5 gr
v² = 1.5 x 9.8 x 47
v = 26.3 m/s
5 inch high
20 inch wide
30 inch long
positive
Step-by-step explanation
the line goes up and to the right
x = 14+
If 14 + 14 = 28
Then
28 > 27 is true.
