Answer:
10.23077 m
55.88391 N/m
Explanation:
m = Mass of person = 58.5 kg
T = Time period =
k = Spring constant
g = Acceleration due to gravity = 9.81 m/s²
Time period is given by
The spring stiffness constant is 55.88391 N/m
The force on spring is given by
The unstreched length of the cord is 20.5-10.26923 = 10.23077 m
Hi there!
Recall the equation for gravitational potential energy:
U = GPE (J)
m = mass (48 kg)
g = acceleration due to gravity (9.8 m/s²)
h = height (21 m)
Plug in the givens and solve.
Answer:
In a biology experiment the number of yeast cells is determined after 24 hours of culture at different temperatures. a) Identify the independent and dependent variables in the experiment. b) Draw the graph of the
Explanation:
Answer:
It is given that the weight of the person is 102 N
We have the force that shall be needed to being the man out in minimum amount of time shall correspond to the maximum tension that can be developed
Thus using Newton's second law we obtain the acceleration that the man shall attain
Now using second equation of kinematics to obtain time 't' we get
