What if a golf ball hit the Earth at the speed of light?
The golf ball would require infinite energy to decelerate, from the speed of light to any number smaller than the speed of light. As any physicist will tell you, the earth will not supply infinite deceleration, so the golf ball will pass clean through the earth.
What if a grain of sand hit the Earth at the speed of light?
The likelyhood that a grain of sand, moving at or near the speed of light, would actually make it to the surface of the earth is so remote as to be ignored. A grain of sand moving at that speed, and hitting the atmosphere, would be destroyed before ever reaching the surface.
What if a penny hit the Earth at the speed of light?
If you give it a push such that it reaches the speed of light you’ll break physics. The penny would melt and break apart from friction before it reached the earth. If it somehow did reach the earths atmosphere intact, it would still be destroyed before reaching the surface.
What happens if a human runs at the speed of light?
The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which they are traveling.
Can the speed of light destroy Earth?
Nowhere near enough energy to destroy even a patch of ground. Light ( if you choose to view it as particles) are a lot smaller than a needle. A needle travelling at the speed of light cannot destroy the Earth.
Can a human punch at the speed of light?
As a result, you would need an infinite amount of energy to match the speed of photons traveling through a vacuum…that’s kind of impossible. Humans just aren’t built for that kind of thing (and that’s not even taking into account what would happen if someone hit the brakes suddenly).
Can humans move at the speed of light?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
Can a human survive going the speed of light?
No, it is not possible for a human to survive travelling at the speed of light. Others have pointed out that it’s impossible to reach the speed of light, so they’re talking about the limits as you approach the speed of light.
What can destroy Earth instantly?
Six cosmic catastrophes that could wipe out life on Earth
- High energy solar flare. Our sun is not as peaceful a star as one might initially think.
- Asteroid impact.
- Expanding sun.
- Local gamma ray burst.
- Nearby supernovas.
- Moving stars.
What is the maximum height a projectile can reach?
Note also that the maximum height depends only on the vertical component of the initial velocity, so that any projectile with a 67.6 m/s initial vertical component of velocity will reach a maximum height of 233 m (neglecting air resistance).
How do you solve problems in projectile motion?
Identify and explain the properties of a projectile, such as acceleration due to gravity, range, maximum height, and trajectory. Determine the location and velocity of a projectile at different points in its trajectory. Apply the principle of independence of motion to solve projectile motion problems.
What happens to the vertical velocity as an object rises?
(c) The velocity in the vertical direction begins to decrease as the object rises; at its highest point, the vertical velocity is zero. As the object falls towards the Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
Why is the initial velocity of an object in space positive?
Note that because up is positive, the initial velocity is positive, as is the maximum height, but the acceleration due to gravity is negative.
