ok so basically
this is what I did
mgh=1/2mv^2
through that i calculated v and got an answer of 7.59 m/s
and then during the swing after jack leaves i calculated the kinetic energy
1/2mv^2=mgh where m=55 and the velocity stays the same
and i got 2.94 m
but then.. it seems...
hey everyone
I am so glad I found this forum
I just have this one question that I need help with:
two circus performers, Jack and Jill, whose total mass is 120 Kg, start a swing which is 5.0 m long such that initially the rope attatched to their swing makes an angle of 36 degrees with the...
