Answer 5

wth

Answer 6

haha i know right

Answer 7

i am not quite sure what to do here

Answer 8

no p,\[F=mgsin \theta\] like before since it's on an inclined plane

Answer 9

ha that means? haha can you show the steps?

Answer 10

\[54\sin \theta = 27\]

Answer 11

\[\sin \theta =27/54 =0.5\]
\[\theta = \sin^{-1} 0.5 = 30^{o}\]

Answer 12

okay i think i got it thanks

Answer 13

no p, God bless
