construction interference is when you build things up and destructive interference is when you tear things down
Answer:
x(spring stretch)=1.74×10⁻³ meter
Explanation:
Given Data
l (length)=0.175 m
v (speed)= 3.86 m/s
x₁(stretch)=0.0140 m
x(spring stretch)=?
Solution
Centripetal force=Spring Constant
as
Spring force = gravitational force
Answer:
The velocity and height is 31 m/s and 44.4 m respectively .
Explanation:
Given :
Initial speed of rock , u = 8.5 m/s .
Time taken to reach ground , t = 2.25 s .
Also , acceleration due to gravity is , .
Now , to find the velocity when it hit ground .
Applying equation of motion :
Also , height from which rock is thrown is given by :
Hence , this is the required solution .
Weather is daily. 'c' is the best choice from this partular list.
