A) 1134
B) 1257
C) 997
D) 1119
Correct Answer: A
Solution :
[a] The acrobat has a force acting on his hand that we resolve into two perpendicular components: the vertical one is the reaction to the weight \[(115\times 9.8N=1127N)\]and the horizontal one balances the 130N force from the wall. These two forces give a resultant force F of \[F=\sqrt{{{1127}^{2}}+{{130}^{2}}}=1134N\]You need to login to perform this action.
