Please solve for the following
Transcribed Image Text:Old naval ships fired 14 kg cannon balls from a 250 kg
cannon. It was very important to stop the recoil of the
cannon, since otherwise the heavy cannon would go
careening across the deck of the ship. In one design, a large
spring with spring constant 2.0×104 N/m was placed behind
the cannon. The other end of the spring braced against a
post that was firmly anchored to the ship's frame.
Part A
