Answer:
Of course harder
Explanation:
Just imagone the floor is wet and you walk on it, do u feel it hard or easy to walk? :D
Answer:
Amplitude will be equal to 0.091 m
Explanation:
Given mass of the slits = 41 gram = 0.041 kg
Frequency f = 1.65 Hz
So angular frequency 
Angular frequency is equal to 

Squaring both side

k = 4.40 N/m
For vertical osculation


A = 0.091 m
So amplitude will be equal to 0.0391 m
Answer:
F = 53153.36[N]
Explanation:
In order to solve this problem, we must first use the principle of conservation of energy which is transformed from potential energy to kinetic, in this way we can determine the velocity at which the person enters the water.

where:
m = mass = 100 [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 9 [m]
v = velocity [m/s]
Now replacing we can determinate the velocity.
![v^{2}=2*g*h\\v=\sqrt{2*g*h}\\v=\sqrt{2*9.81*9}\\v = 13.28[m/s]](https://tex.z-dn.net/?f=v%5E%7B2%7D%3D2%2Ag%2Ah%5C%5Cv%3D%5Csqrt%7B2%2Ag%2Ah%7D%5C%5Cv%3D%5Csqrt%7B2%2A9.81%2A9%7D%5C%5Cv%20%3D%2013.28%5Bm%2Fs%5D)
Then we can calculate the momentum which can be calculated as the product of force by time, this momentum is also equal to the product of mass by velocity.

Now replacing:
F = impact force [N]
t = time = 0.025 [s]
m = 100 [kg]
v = velocity = 13.28 [m/s]
![F*0.025=100*13.28\\F=53153.36[N]](https://tex.z-dn.net/?f=F%2A0.025%3D100%2A13.28%5C%5CF%3D53153.36%5BN%5D)
Hello,
This is true. Net force can be calculated using the equation F = ma, where f is net force, m is mass, and a is acceleration. Simply multiply mass and acceleration to obtain the net force being exerted on the object.
True
Hope this helps!
