A massless spring with spring constant k = 25 N/m is attached at one end of a block of
mass M = 3.0 kg that is resting on a frictionless horizontal table. The other end of the
spring is fixed to a wall. A bullet of mass m = 0.3 kg is fired into the block from the left
with a speed vo= 200 m/s and comes to rest in the block (assume that this happens
instantaneously).

In your job in a police lab, you must design an apparatus to measure the muzzle velocities
of bullets fired from handguns. Your solution is to attach a 2.00 kg wood block that rests
on a horizontal surface to a light horizontal spring. The other end of the spring is attached
to a wall. Initially the spring is at its equilibrium length. A bullet is fired horizontally into the
block and remains embedded in it. After the bullet strikes the block, the block compresses
the spring a maximum distance d. You have measured that the coefficient of kinetic friction
between the block and the horizontal surface is 0.38. The table below lists some firearms
that you will test. A grain is a unit of mass equal to 64.80 mg.

- The spring of a spring gun has force constant k = 406 N/m and negligible mass. The spring is compressed 7.3 cm, and a ball with mass 25 g is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 7.3 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so the barrel is horizontal. What is the greatest speed the ball has along the barrel if a constant resisting force of 7.0 N acts on the ball as it moves along the barrel? (Your result must be in units of m/s and include 2 digits after the decimal point. Maximum of 3% of error is accepted in your answer.)arrow_forwardFrom the Euler-Lagrange equation of motion: = 0, aq dt aqk Show that the equation of motion for this system is given by:arrow_forwardA spring with a spring constant of 335 N/m is initially compressed by a distance of 0.045 m from its equilibrium position.
