Answer:
The stretch cord stores potential energy as a result of stretching but due to kinetic energy, it will move back to its original state. Since air resistance is not being ignored in this case, it will experience a slight delay in stretching at first.
Explanation:
In case, where air resistance is being ignored the stretch cord will stretch as it normally does.
- Air resistance is a force that any object experiences as a result of its motion through the air.
There are various factors that affect air resistance like speed, the density of air, area, the shape of an object etc. Meanwhile, the density of air changes with temperature or altitude. <em>Hence this force is not constant but is thought to be constant during short time frames. </em>
You're thinking of Kepler's first law of planetary motion, but that's not
what it says.
First of all, Kepler didn't say anything about gravity. He only described
the orbits. And he said that the orbit of each planet is an <u>ellipse</u>, with the
sun at one focus.
If by some chance you're thinking of Newton ... he showed that <u>if</u> his formula for
gravity is correct, then the orbit of a planet <u>must</u> be an ellipse. But Newton's law
of gravity is not one of his so-called "three laws of motion".
First, since the echo frequency is greater, the car must be roaming
to the police car.
This is for the reason that the car is "running over" its own wave
fronts, creating the wavelengths tinier, and henceforth increasing the
frequency.
The trick here is to understand that the relative speed between the cars is
half of the speed of the echo for the reason that the echo is returning to the
police car at the similar speed as the sound wave trips to the moving
car.
It would also appear that the speed of sound has been expected to be 337
m/s
So if v is the moving car's velocity, the correct formula to use is:
2v / 337 = (1250/1200) - 1
2v = 14.04 m/s
v = 7.02 m/s
