A gun is fired up. Assuming the air drag on the bullet of mass m varies quadratically with speed as -cx^2 show that the speed varies with height as v^2 = (Ae^-2kx) - g/k during the upwards motion. What is the max height?
Only find the max height. Do not show that the speed varies with height because I already did that.

9) A bullet with mass 0.0075 kg is fired with a gun with mass 0.95 kg. The bullet leaves the gun at 380 m/s. a) What is the recoil speed of the gun? Assume the gun was at rest before firing. b) Is the momentum of the bullet greater, smaller or equal (in magnitude) to the recoil momentum of the gun? c) Find both the kinetic energy of the bullet and of the gun. Which is bigger, or are they...

In a ballistic pendulum, a bullet of mass m is fired into a stationary hanging block of mass M. On impact, the bullet is trapped inside the block, which then slides up to a maximum height of h = 4.06 cm. If the mass of the block (M) is 4.7 times larger than the mass of the bullet (m), determine the speed v which the bullet must have had prior to impact.

Question 1 5 pts In a ballistic pendulum, a bullet of mass m is fired into a stationary hanging block of mass M. On impact, the bullet is trapped inside the block, which then slides up to a maximum height of h - 11.26 cm. If the mass of the block (M) is 2.3 times larger than the mass of the bullet (m), determine the speed v which the bullet must have had prior to impact. M+m m

1. A bullet of mass m -25.0 g is fired into a stationary block of mass m, -4.00 kg, which is suspended on a rope, as shown below. The bullet is initially traveling with velocity v. - 400 m/s, passes through the block and emerges with a final velocity horizontally Immediately after the impact the block travels upward with a velocity of 2.00 m's and reaches a vertical height, h before coming to rest. Determine the maximum height the block...

6. A shell is fired from a gun with a muzzle velocity of 20.0 m's, at an angle of 60.0 with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass. One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that the air drag is negligible? (You may use R-(v/g) sin(20) 7. In...

(hrw8c9p15) A shell is fired from a gun with a muzzle velocity of 23 m/s, at an angle of 60° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (see the figure). One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that the air drag is negligible

A bullet of mass m is fired with a speed v at a wooden block of
mass M which is hanging from the ceiling. The block swings upward
and reaches a maximum height of h. By measuring h, we can find the
initial speed of the bullet v.
a.) Let's say at time t = t0 the bullet has not yet
hit the block. At time t=t1 the bullet/block system is
lodged in the block and the bullet/block system is...
