8) A bullet emerges from the 59.1 cm barrel of a rifle at 905 m/s. Find:...
A rifle fires a bullet. When the bullet leaves the barrel, it has a speed of 125 m/s. If the barrel is 45 cm long, what is the average acceleration of the bullet?
The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by v = (−4.80 ✕ 107)t2 + (2.45 ✕ 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration and position of the bullet as a function of time when the bullet is in the barrel. (Use t as necessary and...
The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by -(-4.05x 107)2(2.45 x 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration and position of the bullet as a function of time when the bullet is in the barrel. (Use t as necessary and round all numerical coefficients to...
If a bullet leaves the muzzle of a rifle with a speed of 600m/s, and the barrel ofthe rifle is 0.9m long, what is the acceleration of the bullet while in the barrel?
A muzzle-loading rifle fires 22LR bullets such that as they travel down the barrel of the rifle their speed is given by v (-4.75 10t2(2.55 x 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration (in m/s) and position (in m) of the bullet as a function of time when the bullet is in the barrel. (Use the following...
1. A bullet leaves a 24 inch rifle barrel at 900 ft/s. What was its acceleration and time in the barrel? 2. A train has an initial velocity of 54 mph. 4 minutes later it slows to a stop at an intersection. What is the acceleration? How far did it travel before coming to a stop?
A 5.00 gram bullet leaves the barrel of a horizontally aimed rifle located 1.00 [m] above the ground with a speed of 250. [m/s]. (a) What is the force on the bullet (assumed constant) as it travels down the 0.500 m barrel of the rifle? (b) How long after leaving the barrel of the rifle is it before the bullet hits the ground? (c) How far does the bullet travel before hitting the ground? Assume air resistance can be neglected.
A rifle has a 0.610 m long barrel. When fired, a bullet with a mass of 11.0 g accelerates from rest and exits the barrel at a speed of 850 m/s. What is the net force on the bullet (in N) while it is in the barrel? ( Enter the magnitude. Assume a constant acceleration)
A rifle with a barrel length of 64 cm fires a 12 g bullet with a horizontal speed of 420 m/s . The bullet strikes a block of wood and penetrates to a depth of 14 cm . A) What resistive force (assumed to be constant) does the wood exert on the bullet? B) How long does it take the bullet to come to rest after entering the wood?
For the sake of directional stability, the bullet fired from a rifle is given a spin angular velocity about its axis by means of spiral grooves ("rifling") cut into barrel. The bullet fired by a Lee-Enfield rifle is (approximately) a uniform cylinder of length equal to 3.18 cm, diameter equal to 0.790 cm, and mass equal to 13.9 g. The bullet emerges from the muzzle with a translational velocity of 622 m/s and a spin angular velocity of 2.78 103...
