The rifle and wood are mounted on separate carts that sit atop an air track (like a linear air hockey table--ie. F is shown in the graph as a function of time. The arrow sticks in the block. A particle of mass m, initially at rest, is acted upon by a variable force F for a brief interval of time T. It begins to move with a velocity u after the force stops acting. A rifle of mass M is initially at rest but free to recoil. 35. Bullets from two revolvers are fired with the same velocity. After firing, the velocity of the rifle (relative to the ground) is: A. Determine its velocity v as a function of time. They start moving towards the centroid due to mutual force of attraction. The mass of the rifle is 4.50 kg. When ‘F’ is shown in the graph as a function of time the curve is a semicircle as shown in the figure . The graph After firing, the velocity of the rifle (relative to the ground) is: −mv/M. If the tabletop is 1 m above the floor, how long does it take for the combined object to fall to the ground? A block of mass M is initially at rest on a frictionless floor. At time t = 0, a force given by F = F 0 te -λ t is applied. Two masses 'm' and 2m' with speed 2v and v (as shown) strike the rod and stick to the rod. Two gliders collide on a frictionless air track that is aligned along the x axis. If the length of the barrel is 75 cm, what is the the average force that accelerates the bullet? The bullet remains in the block, and after impact the block lands a distance d from the bottom of the table. The bullet passes through the block and emerges with its speed reduced to 190 m/s. A uniform rod of length '6L' and mass '8m' is pivoted at its centre 'C'. P9.45). Homework Statement A particle of mass m, initially at rest at x=0, is accelerated by a force that increases in time as F=Ct 2. frictionless). 1 Answer Cesareo R. Mar 14, 2018 #3/5 E#. Momentum is always conserved. Choose the correct relation of the following.

An object of mass m = 9.6 g is fired into a larger object of mass M = 310 g that was initially at rest at the edge of a table. When a 0.015-kilogram bullet leaves the gun with a Calculate the velocity v(t) of the object as a function of time. Nov 22 2013 08:47 PM. (a) u = πF 0 2 / 2m (b) u = πT 2 / 8m (c) u =πF 0 T / 4m (d) u = F 0 T / 2m the answer is 0 kg times m/s:why?? rifle that is initially at rest. If the bullet leaves the rifle with momentum having a magnitude of 20. kilogram•meters per second, the rifle will recoil with a momentum having a magnitude of A) 0.0 m/s B)2.4 m/s C) 7.5 m/s D) 500. m/s 16.A 3.1 kilogram gun initially at rest is free to move. Initially the blocks are at rest and the spring is unsrtretched when a constnt force F starts acting on the block of mass M to pull it. It fires a bullet of mass m and velocity v (relative to the ground). mass m is initially at rest when there is no extension. An arrow with mass m and velocity v is shot into the block. What are the velocities of the stars just before the collision? Three stars each of mass M and radius R are initially at rest and the distance between centres of any two stars is d and they form an equilateral triangle. The combined mass of the gun and projectile is M 2 If the kinetic energy of the projectile after firing is K, the gun will recoil with a kinetic energy equal to (A) K (B) (M 2 /M 1)K (C) (M 2 1 /M 2 2)K (D) (M 1 /(M 2 - M 1))K (E) √(M 1 /(M 2 - M 1))K A rifle bullet of mass m = 0.03 kg traveling at vb = 240 m/s collides with and embeds itself in a pendulum of mass M = 2.88 kg, initially at rest and suspended vertically by massless strings of length L = 2 m. A bullet of mass 6.45 g is fired from a 66.0 cm-long rifle barrel at 237 m/s. It begins to move with velocity ‘u’ after the force stops acting. The second 4-kilogram mass then collides head-on and Explanation: Conservation #2m v_1 + 3m v_2 = 0# Energy. the velocity of third fragment is An object of mass m, initially at rest under the action of a constant force F attains a velocity v in time t. Then, the average power supplied to mass is 3.7 k Q9.15 A sharpshooter fires a rifle while standing with the butt of the gun ... initially at rest, explodes into several pieces. 81. Calculate x(t) and v(t). A block of mass m is connect to another block of mass M by a massless spring of spring constant k. The blocks are kept on a smooth horizontal plane. Now if the mass is released suddenly, then the maximum elongation in the spring is Share with your friends. They are then allowed to move towards each other under mutual gravitational attaction. (a) What is the speed of the block of mass M? therfore m×v= constant m×v= (M+m)×V V is the velocity of embedded system V = (m×v)/(M+m) Share 3. A 0.0250-kg bullet is accelerated from rest to a speed of 550 m/s in a 3.00-kg rifle. The curve is a semicircle. The 5.7 kg rifle fires a 27 . 6) A 2.0 kilogram rifle initiatlly at rest fires a 0.002 kilogram bullet.
