Explanation:
Answer:
it is 27 degree.
Explanation:
because angle of reflection is equal to angle of Inc dence
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>
