1. The problem statement, all variables and given/known data ok, so i need to find max velocity and force of friction of a model rocket. The rocket weights 83.8 g, accelerates at 5.78 m/ss. Its max height is 84.99 m. plz help 2. Relevant equations ok for Ff = μkFn as for Vmax i have no idea 3. The attempt at a solution ok so i found Fn = 82.266 N cuz u have to convert grams to kg. Thats all i can figure out.
