Example

Problem: A 10.0 kg wood ball hangs from a 1.30 m-long wire. The maximum tension the wire can withstand without breaking is 600 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?

FREE Expert Solution

If we let v0 be the velocity of the ball and the projectile, then we'll have:

T=(M+m)g+(M+m)v02l(M+m)v02l=T-(M+m)gv0=l[T-(M+m)g]M+m=(1.30)[600-(10.0+0.900)(9.81)]10.0+0.900
