Answer:
5.62 m/s
Explanation:
Newton's law of motion can be used to determine the maximum speed of the elevator. In the question, we are given:
Force exerted by the elevator (R) = 1.7 times the weight of the passenger (m*g)
Thus: R = 1.7*m*g
Distance (s) = 2.3 m
Newton's second law of motion: R - m*g = m*a
1.7*m*g - m*g = m*a
a = 0.7*m*g/m = 0.7*g = 0.7*9.8 = 6.86 m/s²
To determine the maximum speed:
Therefore, the elevator maximum speed is equivalent to 5.62 m/s.
Answer:
Regions near rivers have water surfaces that rapidly change in temperature from cold to hot.
you have your own answer i only selected which is suitable for me . none of them is wrong they re excellent
Answer:weak nuclear
Explanation:
There weak nuclear force is responsible for allowing carbon-14 to become stable
The block Z would be seen in figure 10 when 4 strident turn around
Because when the resistance will be decreased there will be less collision among electrons and protons and electrons can flow easily do the current can flow easily.
