When a car stops, its instantaneous speed becomes zero.
Because when moving at the speed of light, time stops for you and you can no longer measure speed (distance covered in a certain time).

The instantaneous velocity at the maximum height is zero because the object momentarily stops moving before falling back down due to gravity.
The energy to produce the light stops and the light stops.
Actually, the closest star to Earth is Sun which would be reached in a little more than 8 minutes.As for other stars, closest one is Proxima Centauri. You'd need to travel for 4 years and 2 months to reach it at the speed of light. You may or may not know that you have asked a delightful trick question. If I were traveling at the speed of light [impossible, of course] how long would it take me to get to earth's nearest star? From my point of view, the trip would be instantaneous. It would also be an instantaneous trip if I traveled to a destination 100 million light years away. Time completely stops at light speed. Observers on earth would conclude that the trip took me 8 minutes. We would all be right, within the scope of our individual frames of reference.
It would be if it wasn't for the fact that time relative the object moving at high speed slows down as you approached the speed of light, and completely stops when you reach it. This is what prevents things from going faster than the speed of light.
You need to know the Einsteins equation of relativity. t'=t(1-v2/c2)0.5 Basically this says the time (t') is relative to velocity (v). And C is the speed of light If v=c you get: t'=t(1-1)0.5=tx0 Therefore time stops for you when you reach the speed of light.
Even at modest %'s of the speed of light objects start to radiate their energy away in Gravitational Waves. So it is very expensive to approach the speed of light when most of your effort is just radiated away.
97mph is when the speed regulater stops you.
It will depend on your speed plus comfort stops, refreshment stops, refuelling stops.
A 9 ND filter reduces the light by 9 stops.
