Answer:
The nest must be about 4.15 meters above ground
Explanation:
Use the velocity equation under accelerated motion (acceleration of gravity ):
which for this case has initial velocity = 0 (falls from the nest), final velocity = 9 m/s, and a = 9.8 m/s^2, then we can find the time needed in air while falling to reach the required speed:
We now use this time value to find the distance covered in free fall during 0.92 seconds:
Answer:
110.25 J
Explanation:
We are given that
Mass,M=2.5 kg
Radius,R=0.5 m
Distance,d=4.5 m
Initial speed,u=0
We have to find the total kinetic energy
According to law of conservation of energy
Total kinetic energy=Potential energy=mgh
Where g=
Using the formula
Total kinetic energy=
Total kinetic energy
Answer: 44 N/m
Explanation:
Finding the interatomic spring stiffness
Because in our model all the bonds are assumed to be the same, the interatomic spring stiffness ks, interatomic is determined by adding the springs . The details of that addition are below, but the final result is that the interatomic spring stiffness is related to the spring stiffness of the wire like so:
