Hello,
I have difficulties with this problem:
The body mass m1 = 20 g is fired with a spring, k = 72 N / m from position A. On arrival at point B hits completely elastic body mass m2 = 15 g.
Find the distance x of compressed spring so that the mass m2 reaches point C separated a distance d = 90 cm from point O. Data: h = 25 cm.
I was trying to do the calculations and camera up with these:
Since momentum P and cinetic energy are constant therefore m1*v0=m1v1+m2v2 and 1/2m1v0=1/2m1v1 +1/2m2v2
To find the v2 of the object m2 I apply conservation of energy law and it sums up to 1/2m2v2 = m2gh
After making calculations I get stuck and I think I'm missing something.
Please give an advice with this.
Thanks
