Click For Summary
Rocket-powered dragsters, particularly those using hydrogen peroxide, can achieve remarkable speeds, with a record quarter-mile time of 3.22 seconds. Weight plays a critical role in determining both acceleration and top speed, as lighter vehicles can accelerate faster under constant thrust. Unlike traditional wheel-driven dragsters, rocket engines maintain consistent thrust throughout the run, allowing for sustained acceleration despite increasing drag. The discussion highlights the differences in performance dynamics between rocket-powered and wheel-driven vehicles, emphasizing that while both types face drag challenges, the constant thrust of rockets provides a significant advantage. Ultimately, the interplay of weight, thrust, and drag is crucial in understanding the speed capabilities of these high-performance vehicles.

So, we can record and take a picture of light in vacuum? I thought light don't actually accelerating because light is supposed to be already there even before we started to record or take a picture of it.
