- A battleship that is 5.00 x 107 kg and is originally at rest fires a 1300-kg artillery shell horizontally with a velocity of 550 m/s. (a) If the shell is fired straight aft (toward the rear of the ship), there will be negligible friction opposing the ship's recoil. Calculate its recoil velocity in meters per second. 0.0143 m/s (b) Calculate the increase in internal kinetic energy in joules (that is, for the ship and the shell). This energy is less than the energy released by the gun powder – significant heat transfer occurs. Additional Materials O Readinga particle of mass .260kg moves head on with a velocity .534x+.374y m/s toward a second particle of mass .486 kg placed on a smooth horizontal table. here x and y are unit vectors along the x and y axis. the collison is completely inelastic. the energy lost in this collision is?Two equal mass objects undergo a perfectly elastic collision. One object is moving with a velocity v and the other is initially at rest. The collision is not head-on (two dimensional). Show that the two objects move away from each other perpendicularly (the velocity vectors of the two objects after the collision make a right angle).

The bullet remains in the block, and after the impact the block lands d = 1.50 m from the bottom of the table. Determine the initial speed of the bullet. Use the given information to find the velocity of the block after collision with the bullet and then use conservation of momentum to find the initial speed of the bullet. m/s Need Help?
