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:
"Gravitational force and the acceleration force" are the forces that are acting on a passenger while going through a loop.
Explanation:
When the passengers reach the top of the loop, The force of the car's acceleration pushes all the passengers off the seat and towards the center of the loop. On the other hand the inertia will try to push the passengers back into the seat. The gravity as well as the acceleration will tend to push the passenger in opposite direction with approximately equal force, which will create a feeling of being mass-less or we can call it weightlessness.
Answer:
2 times
Explanation:
Given:
u = 10 m/s
v = 20 m/s
To Find:
Factor of change in Momentum = ?
Solution:
Final Momentum = mv
Final Momentum = m(20)
Final Momentum = 20m
Initial Momentum = mu
Initial Momentum = m(10)
Initial Momentum = 10m
Therefore, Factor of change in Momentum = 20m / 10m = 2 times
PLZ MARK ME AS BRAINLIEST!!!
I would say C. if im wrong, im sorry. but if im right your welcome. i didnt guess tho.
Yes, I do! Vectors have a direction linked to them and scalars don’t.
