physics I'M STUCK PZL HELP
hai Teresa can u help me for this Rocket question i don't know how to get 0.955 in the above ans ! Consider a rocket in space that ejects burned fuel at a speed of vex= 2.0 km/s with respect to the rocket. The rocket burns 11 % of its mass in 250 s (assume the burn rate is...
