Thanks in advance for the help. I'm stuck on problem #12(please see the attached file). I did this:(adsbygoogle = window.adsbygoogle || []).push({});

r= cos(26)*2.8(is this right?)

r= 2.52

a= mg/(cos(ang))

r*a=v(squared)

a= 5.9(9.8)/cos(26)

a= 64.3

v= sqrt(2.52*64.3)

v= 12.7

What's wrong with this?
