Agent Arlene devised the following method of measuring the muzzle velocity of a rifle (the figure below). She fires a bullet into a 4.114-kg wooden block resting on a smooth surface, and attached to a spring of spring constant k = 164.2 N/m . The bullet, whose mass is 7.870 g, remains embedded in the wooden block. She measures the maximum distance that the block compresses the spring to be 9.460 cm .
What is the speed v of the bullet?

Agent Arlene devised the following method of measuring the muzzle
velocity of a rifle (the figure below). She fires a bullet into
a 4.293-kg wooden
block resting on a smooth surface, and attached to a spring of
spring constant k = 162.8N/m. The bullet, whose mass is 7.870 g, remains embedded in the wooden block. She measures the maximum
distance that the block compresses the spring to
be 9.460cm.What is the speed v of the bullet?

A skeet shooter aims at a clay pigeon. The muzzle velocity of
the rifle is 700 mph and the man holds the rifle such that the end
of the gun is 6 ft off the ground. Assuming that the speed of the
skeet is insignificant relative to the speed of the bullet,
determine the angle at which the man needs to hold the rifle in
order to hit a clay pigeon that is 50 yards away and at an altitude...

The following data represent the muzzle velocity (in feet per
second) of rounds fired from a 155-mm gun. For each round, two
measurements of the velocity were recorded using two different
measuring devices, resulting in the following data. Complete parts
