Heavier objects do not fall faster than lighter objects when they are dropped from a certain height IF there is no resistance from the air. So, if you were in a vacuum, the two things would fall at the same rate.

Explanation:
Mass of roller coaster=m=1040 kg
Radius=r=24 ,
a.
Normal force=
According to question
Where
Substitute the values
b.
<u>We are given:</u>
2 Vectors A and B
A = î - 5j
B = 2î - 10j
<u>Proving that the given vectors are Parallel:</u>
We can rewrite the Vector B as: B = 2(î - 5j)
Since A = î - 5j
Vector B can be written as:
B = 2(A vector)
this means that the magnitude of Vector B is twice of vector A but their direction is the same
Since the 2 vectors are moving in the same direction, they are parallel
