A rifle with a weight of 20 N fires a 5.5-g bullet with a speed of 210 m/s. (a) Find the recoil speed of the rifle. m/s (b) If a 675-N man holds the rifle firmly against his shoulder, find the recoil speed of the man and rifle. m/s

1. A hunter on a frozen, essentially frictionless pond uses a rifle that shoots 4.20 g bullets at 965 m/s. The mass of the hunter (including his gun) is 72.5 kg, and the hunter holds tight to the gun after firing it. Find the recoil velocity of the hunter if he fires the rifle: a. horizontally and b. at 56.0°above the horizontal.

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0235 kg0.0235 kg and the mass of the pendulum is 0.250 kg,0.250 kg, how high ℎh will the pendulum swing if the marble has an initial speed of 5.35 m/s?5.35 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision.

A 1.72 kg block of soft wood is suspended by two strings from the ceiling. The wood is free to rotatein pendulum-like fashion when a force is exerted upon it. An 8.5 g bullet is fired into the wood. Thebullet enters the wood at 431 m/s and exits the opposite side shortly thereafter. If the wood rises to aheight of 13.8 cm after the collision, then what is the exit speed of the bullet?

A 3.00-g bullet is fired horizontally into a 10.0-kg block of wood suspended by a rope from the ceiling.  The bullet becomes embedded in the wood, and, as the result, the block swings up in an arc, like a ballistic pendulum, rising 3.00 mm above its original position.  Which of the following is the closest to the initial speed of the bullet? Group of answer choices a. 235 m/s b. 24.3 m/s c. 75.0 m/s d. 811 m/s e. Cannot be determined since the heat generated in the collision is       unknown

A 10 kg cannonball is fired horizontally to the left out of a 1700 kg cannon. The cannonball leaves the muzzle at −600x^ms−600x^ms. The recoil velocity of the cannon  is Answer

1. A bullet of mass m, = 0.0500 kg is fired into a block of wood of mass m₂ = 0.850 kg. This block of wood is hanging from light wires. The bullet embeds in the block and the bullet and block combined swing up to a height of h=0.350 m. What was the speed of the bullet (vu) right before it hit the block of wood (ignore friction)? a. 4.64 x 10³ m/s b. 2.62 m/s c. 44.5 m/s d. 47.1 m/s e. 123 m/s

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0235 kg and the mass of the pendulum is 0.250 kg, how high h will the pendulum swing if the marble has an initial speed of 5.65 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision. h = m

A gun fires a bullet vertically into a 1.40-kgkg block of wood at rest on a thin horizontal sheet. If the bullet has a mass of 13.5 g and a speed of 310 m/s, how high will the block rise into the air after the bullet becomes embedded in it? Answer in meters.
