what applied force is needed to accelerate 50kg at 2m/s^2 if the friction force is 200
You and your younger brother are designing an air rifle that will shoot a lead pellet with mass m = 1.00 g and cross-sectional area A = 0.0150 cm2. The rifle works by allowing high-pressure air to expand, propelling the pellet down the rifle barrel. Because this process happens very quickly, no appreciable thermal conduction occurs and the expansion is essentially adiabatic. Your design is such that, once the pressure begins pushing on the pellet, it moves a distance of...
A 4.0-g bullet leaves the muzzle of a rifle with a speed of 328 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.75-m-long barrel of the rifle? A 4.0-g bullet leaves the muzzle of a rifle with a speed of 328 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.75-m-long barrel of the rifle? 765 Your response differs from the correct answer by more...
