The fuel burns exerting a time-varying force on the small 2.00 kg rocket model during its vertical launch. This force obeys the equation F= A + Bt2. Measurements show that at t=0, the force is 25.0 N, and at the end of the first 2.00 s, it is 45.0 N. Assume that air resistance is negligible. find the constant A and B, including SI units using the equation F=A+Bt^2. a. What are the forces acting on the rocket? b. Draw it's free-body diagram. c. Find the constant A and B, including SI units using the equation F= A+Bt^2? d. Find the net force on this rocket and it's acceleration the instant after the fuel ignites? e. Find the net force on this rocket and it's acceleration 3.00 s after fuel ignition? f. Suppose you were using this rocket in outer space, far from all gravity. wha would it's acceleration be 3.00 s after fuel ignition? g. What is the rockets mass in outer space? what is its weight?
