The recoil of a shotgun can be significant. Suppose a 3.0-kg shotgun is held tightly by an arm and shoulder with a combined mass of 15.0 kg Part A When the gun fires a projectile with a mass of 0.032 kg and a speed of 380 m/s, what is the recoil velocity of the shotgun and arm–shoulder combination? Express your answer to three significant figures and include appropriate units.

A car, with a mass of 1240 kg, is moving towards an intersection at a velocity of 26.6 m/s towards the South. At the intersection, it collides with a truck that has a mass of 1580 kg and is moving with a velocity of 14.0 m/s towards the West. When they collide, the two vehicles stick together. 15. The magnitude of the final velocity for the car and truck is Answer to 3 significant digits. m/s. (Record your answer in the numerical-response section below.) Your answer:

A bullet with a mass of 4.00 X 10^-3 is loaded into a gun. The loaded gun has a mass of 6.82 kg. The bullet is fired, causing the empty gun to recoil at a speed of.0.25 m/s. What is the speed of the bullet? Note: Please show all of the steps so that I can understand what i am supposed to do. Too many times the experts do not show all of the steps. I do not understand Physics.

A bullet of mass m = 8.00 g is fired into a block of mass M = 220 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.60 m from the bottom of the table. Determine the initial speed of the bullet. __ m/s

A blue puck with a mass of 4.50×10-2 kg. sliding with a velocity of 0.230 m/s North on a frictionless, horizontal air table, makes a perfectly elastic, head-on collision with a red puck with mass m, initially at rest. After the collision, the velocity of the blue puck is 5.0×10-2 m/s North. ▼ ▼ Part A Find the momentum of the red puck after the collision. Give the horizontal component with North positive.

The figure below shows a bullet of mass 230g traveling horizontally towards the east with a speed of 415m/s, which strikes a block of mass 7.5kg that is initially at rest on a frictionless table. After striking the block, the bullet is embedded in the block and they begin to move as one unit.  A. What is the magnitude (in m/s) and direction of the velocity of the block/bullet unit immediately after the impact? B. What is the magnitude (in N * s) and direction of the of the impulse of the block on the bullet?  C. What is the magnitude ( in N *s) and direction of the impulse of the bullet and the block?
