How do I make my recordings "speed up?

Obviously, we can make rockets to go very fast, but what is a reasonable top speed?

• Obviously, we can make rockets to go very fast, but what is a reasonable top speed? Assume that a rocket is fired from rest at a space station in deep space, where gravity is negligible. A)If the rocket ejects gas at a relative speed of 1300 m/s and you want the rocket's speed eventually to be 1.00×10−3c , where c is the speed of light, what fraction of the initial mass of the rocket and fuel is not fuel? B)What is this fraction if the final speed is to be 3300 m/s ? any and all help will be appreaciated

• Answer:

  Part A: I am assuming you mean 1*10^-3*c for final speed Vi=0 use the formula: Vf-Vi=Vexhaust*ln(m0/m) 1*10^-3*3*10^8=1300*ln(m0/m) 300000=1300*ln(m0/m) 230.77=ln(m0/m) 1.67*10^100=m0/m 5.996*10^-101=m/m0 Part B: Just use the same formula, only now the final velocity is 3300m/s
