WebOne of the most difficult tasks with which NASA has had to deal is how its space systems operate while transiting the atmosphere as they return to Earth. Coming home after a flight into space is fundamentally a challenge that has involved over the years critical contributions from engineers working in aerodynamics, thermal protection, guidance and … WebDrag force FD is proportional to the square of the speed of the object. Mathematically, FD = 1 2CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ …
WebIn the equation V = d/t, V is the velocity, d is the distance, and t is the time. Determine the object’s acceleration by dividing the object’s mass by force and multiply the answer by the time it took for it to accelerate. For example, if the object weighs 30 kg and has a force of 15 N applied to it, then the acceleration would be 4 m/s.
WebIt can be calculated using the equation. acceleration = resultant force ( newtons, N) divided by mass (kilograms, kg). One model rocket has a mass of 50 grams and a rocket engine … hankchatWebthe formula h=vt-16t^2 gives the height h in feet of an object after t sec.
