Answer:

Explanation:
It is given that,
Mass of Albertine, m = 60 kg
It can be assumed, the spring constant of the spring, k = 95 N/m
Compression in the spring, x = 5 m
A glass sits 19.8 m from her outstretched foot, h = 19.8 m
When she just reach the glass without knocking it over, a force of friction will also act on it. Using the conservation of energy for the spring mass system such that,




So, the coefficient of kinetic friction between the chair and the waxed floor is 0.101. Hence, this is the required solution.
Example: A apple rotting.
If I put my apple in a fridge, then it would not rot as fast because it is in a cooled area. (example)
Hope it helps! Brainiest Answer would be amazing!
I think it’s D) all of the above
Answer:
141.42 km/h
Explanation:
Since this is a 100km/h right angle crosswind, the speed vector with respect to the ground is the vector speed of the airplane with respect to air + the vector speed of the cross-wind with respect to the ground
<100,0> + <0,100> = <100,100>
This vector has a magnitude of
km/h
