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 68 kg human sprinter can accelerate from rest to 10 m/s in 3.3 s . During the same time interval, a 25 kg greyhound can go from rest to 20 m/s. Part A What is the average power output of the human? Average power over a time interval Δt is ΔE/Δt. Express your answer to two significant figures and include the appropriate units. Part B What is the average power output of the greyhound? Express your answer to two...
1-A football punter accelerates a football from rest to a speed of 10 m/s during the time in which his toe is in contact with the ball ( about 0.20 s). If the football has a mass of 0.50 kg, what average force does the punter exert on the ball? 2- A 5.0 g bullet leaves the muzzle of a rifle with a speed of 320 m/s. What force ( assumed constant) is exerted on the bullet while it is...
