Question
Q. A 20 kg wooden ball hangs from a 2.0-m-long wire. The maximum tension of the wire
can withstand without breaking is 400 N. A 1.0 kg projectile, traveling horizontally immediately
before the collision, hits and embeds itself in the wood ball.
1.Could you please show a free body diagram of the wooden ball immediately after the collision?
2. Could you please show which direction the following force act?
(M+m)v²/l where M= 20kg, m=1kg , l= 2m and v is the finial velocity
Tmax = (M+m)g - (M+m)v²
I am confuse yellow highlighted part
Explanation / Answer
mv^2/r=600N m=20 r=1.5 solve for v ..... v=6.71m/s v=(m(proj.) v(proj.)) / (m(proj) + (20)) (6.71m/s)= ((.8) v(proj)) / ((.8) + (20)) v(proj) = 174.4m/s
