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: A) because forces are what stop and start motion
Explanation:
From Newton's first law, an object tends to stay in state of rest or motion unless acted upon by an unbalanced external force. This is also known law of inertia. This is because a force can stop or start a motion. A force cause body to accelerate to decelerate otherwise the body continues with constant speed.
Hello.
<span>The Hudosn River
It flows over rock that has been around since the Middle Proterozoic Time Period. That is more then 542 million years ago.

Have a nice day
Larger rocks are broken into smaller pieces through weathering and carried away from their original location by <u>B. Erosion</u>
Erosion usually happens when a water source, wind source or some type of source hits a rock. Most of the time these sources displace the rock, or move the rock, away from its original position
Part a)
since steelhead jump under the influence of gravity
So we will use kinematic equations
here at the maximum position we know that final speed will be zero
now we will have
so the maximum height that it can reach will be 3.26 m
Part B)
now if it reaches to height 1.8 m with initial speed 8 m/s
so here we will have
