How long does it take a bullet to pass through a board?

A bullet traveling horizontally at a speed of 350 m/s hits a board perpendicular to the surface, passes through and emerges on the other side at a speed of 210 m/s. The board is 0.04 m thick, how long does the bullet take to pass through it?

Solution Summary

This solution calculates the time it takes a bullet to pass through a board.

A 136 g bullet is fired from a rifle having a barrel 0.935 m long. Assuming the origin is placed where the bullet begins to move, the force exerted on the bullet by the expanding gas is F = a + bx - cx^2, where a = 20600 N, b = 5680 N/m, c = 39900 N/m^2, with x in meters.
Determine the work done by the gas on the bullet as th

A 5.00-g bullet is shot through a 1.00-kg wood block suspended on a string 2.000 m long. The center of mass of the block rises a distance of 0.45 cm.Find the speed of the bullet as it emerges from the block if its initial speed is 450 m/s.

A gun fires a bullet of mass 17 grams out of a barrel 24 cm long. The bullet is accelerated down the length of the barrel with an average force of 16 Newtons.
Using the Impulse-Momentum Theorem, determine the velocity with which the bullet exits the barrel.
What average force is exerted by the individual holding the gun

A 90g bullet is fired from a rifle having a barrel 0.690m long. Assuming the origin is placed the bullet begins to move, the force (in newtons) exerted on the bullet by the expanding gas is 1000 + 6000x- 35000x*x where x is in meters.
a) Determine the work done by the gas on the bullet as the bullet travels the length of the

A 12.0-g rifle bullet is fired with a speed of 380 m/s into a ballistic pendulum with with mass 6.00 kg, suspended from a cord 70.0 cm long. Compute the vertical height through which the pendulum rises. Compute the initial kinetic energy of the bullet. Compute the kinetic energy of the bullet and pendulum immediately after the b

Suppose a bullet is fired on a distant planet so that its height (in feet) after t seconds is given by h=-4t2 + 16t +5.
The 2 in 4t2 is a small 2, but I don't know how to do that with my keyboard.
a. When is the bullet at its highest point?
b. When will the bullet strike the ground?
c. What is the maximum height the bu

You need to verify which gun fired a bullet in a police investigation with a very limited budget. There are two guns involved in a crime; both could fire bullets of the same kind of mass (0.1kg). One is an assault rifle which fires the bullet at speed of 300m/s; the other is a hand gun which fires the same bullet with speed of 2

A plane initially flying at 120 m/s [E] accelerates at 5.6 m/s^2[W] for 20.0 s.
a)What is plane's final velocity?
b) What is plane's displacement in this time?
A bullet leaves the muzzle of a gun with a velocity of 410m/s. The length of the gun barrel is 0.50m.
a) What is average velocity of the bullet inside the barrel of

A 2.00-g bullet hits and becomes embedded in a 5.00-kg wood block which is hanging from a 1.20-m long string. This causes the block to swing to a height of 2.24mm. What was the speed of the bullet before it hit the block?
