Answer:
No we cannot perform any experiment that tells us weather we are moving or not at a constant speed.
Explanation:
Motion of any body is relative to other reference bodies. We can perceive motion only if our position with respect to a fixed object changes. This is the fundamental concept of reference frame in classical physics or Newtonian Physics that motion is always from a reference.
We choose a fixed body as reference and ,measure the distance we cover from this fixed point and also our speed with respect to this fixed point. The choice of frame of reference is completely dependent on the observer.
Since in the given case a reference cannot be established outside the plane thus we cannot detect our motion.

A comet speeds up as it approaches the Sun. Which statement about its kinetic energy is correct option is - (1) The comet has no kinetic energy because it is in outer space.
- Large ice and dust-based bodies known as comets circle the Sun. These ancient objects, which are best known for their long, streaming tails, are relics from the solar system's birth 4.6 billion years ago. The majority of comets are located outside of our solar system. Some are found in the Kuiper Belt, a vast disc that extends past Neptune's orbit. These are known as short-period comets. They orbit the Sun in lesser than 200 years.
- The Outermost Layer, the solar system's sphere-shaped outer edge, which is nearly 50 times further from the Sun than the Kuiper Belt, is home to additional comets. Because of how much longer it takes them to orbit the Sun, these are known as long-period comets. The comet with the longest known orbit completes one orbit in excess of 250,000 years.

Answer:
4.408 m.
Explanation:
Given:
m = 72.1 kg
vf = 9.3 m/s
vi = 0m/s
a = 9.81 m/s^2
Equations of motion:
i. vf = vi + a*t
ii. S = vi*t + 1/2*(a*(t^2))
iii. vf^2 = vi^2 + 2a*S
Using iii. equation of motion;
(9.3)^2 = 0 + 2 * (9.8) * S
S = 86.49/19.62
= 4.408 m.
