WebAug 7, 2024 · (10.3.3) v = V ln m 0 m 0 − b t. The acceleration is (10.3.4) d v d t = V b m 0 − b t. At t = 0, the speed is zero and the acceleration is V b m 0. At time t = m 0 b, the remaining mass is zero and the speed and acceleration are both infinite. However, this is so only if the initial mass is 100% fuel and nothing else. This is not realistic.

WebThe Math / Science The formula for the velocity based on the length of skid marks is: v = √30⋅ L⋅ f c v = 30 ⋅ L ⋅ f c where: v = initial velocity L = Length of Skid Marks fc = friction coefficient (0.05 for very slippery to 0.9 for ultimate breaking) Braking Coefficient The Braking Coefficient is a coefficient of kinetic friction. WebThe maximum velocity of our rocket ideally will be 64.03 m/s or 143 mph. Now let’s figure our altitude after the rocket motor burns. Using equation 3: Our rocket altitude at motor burnout is 10.24 meters or 32 feet above the ground theoretically. Using equation 4 we can find out the total theoretical altitude that our rocket will go.
