Answer:
0.68 seconds
Explanation:
Data provided in the question:
Mass of the box = 50 kg
Speed of the box = 1.0 m/s
Coefficient of friction, μ = 0.15
Now,
Force applied = μmg
Here,
g is the acceleration due to gravity = 9.8 m/s²
Thus,
F = 0.15 × 50 × 9.8
= 73.5 N
Also,
Force = Mass × Acceleration
thus,
73.5 N = 50 × a
or
a = 1.47 m/s²
After doubling the speed
Final speed = 2 × Initial speed
= 2 × 1 m/s
= 2 m/s
Also,
Acceleration = [change in speed] ÷ Time
or
1.47 = [ 2 - 1 ] ÷ Time
or
Time = 1 ÷ 1.47
or
Time = 0.68 seconds

From a quick scan, the quakes happen along plate boundaries as in tectonics. this is when a few trillion (1000 000 000 000) tons of earth move, albeit slowly, relative to each other, and various places feel the enormous forces generated. There is also the "ring of fire" which could be associated here as in the lines where volcanic activity occurs - witness Mt Etna, Sicilia, Italia, Europe at the moment.
Relative movements of these tons of earth can be head on (forming lumps in the earth aka ridges and mountains) or sliding against each other. Not wise places to go for relaxing quiet holidays ... unless the holiday maker is addicted to risk.
