Answer:
Mass of fish=6.252 kg
Explanation:
Force F=0 N to 250 N
Length x=15.0 cm=0.15 m
Frequency f=2.60 Hz
To find
Mass of fish m
Solution
First we need to find spring constant

As we know that the time period is given as

Answer:
t = 2.2 s
Explanation:
Given that,
Height of the roof, h = 24.15 m
The initial velocity of the pumpkin, u = 0
We need to find the time taken for the pumpkin to hit the ground. Let the time be t. Using second equation of kinematics to find it as follows :

Here, u = 0 and a = g

So, it will take 2.22 s for the pumpkin to hit the ground.
Answer:
SUPONIENDO QUE NO HAY FRICCIÓN
Explanation:
F = 66 kg(
) = 132 N
Explanation:
a) We need to write down first Newton's 2nd law as applied to the given system. The equations of motion for the x- and y-axes can be written as follows:


From Eqn(2), we see that

so using Eqn(3) on Eqn(1), we get

Solving for the acceleration, we see that


b) Now that we have the acceleration, we can now solve for the velocity of the crate at the bottom of the plane. Using the equation

Since the crate started from rest,
Thus our equation reduces to
