Let the mass of the wood ball to be M and the mass of the projectile to be m.
The maximum tension is then given as:
A 20.0 kg wood ball hangs from a 2.10 m-long wire. The maximum tension the wire can withstand without breaking is 400 N. A 0.900 kg projectile traveling horizontally hits and embeds itself in the wood ball.
What is the largest speed this projectile can have without causing the cable to break?
