Q1. A 10.0g bullet is fired horizontally into a 106g wooden block that is firstly at rest on a frictionless horizontal surface and connected to a spring of constant 160 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 84.0 cm, what was the speed of the bullet at impact with the block?

Q2. A 20.0 kg wood ball hangs from a 1.3 m long wire. The maximum tension the wire can withstand without breaking is 300 N. A 0.70 kg projectile travelling horizontally hits and embeds itself in the wood ball.
