Answer:
c it is not accelerating on it's on but gravity pulls it there for velocity increases.
Answer:
v = 3.84 m/s
Explanation:
In order for the riders to stay pinned against the inside of the drum the frictional force on them must be equal to the centripetal force:

where,
v = minimum speed = ?
g = acceleration due to gravity = 9.81 m/s²
r = radius = 10 m
μ = coefficient of friction = 0.15
Therefore,

<u>v = 3.84 m/s</u>
Answer:
4.1666666 seconds
Explanation:
100 divided by 24 will give you about 4.1666666 seconds or 4 1/6 seconds. Hope it helps!
