A) 56 m
B) 64 m
C) 80 m
D) 128 m
Correct Answer: C
Solution :
\[{{S}_{x}}={{u}_{x}}t+\frac{1}{2}{{a}_{x}}{{t}^{2}}\Rightarrow {{S}_{x}}=\frac{1}{2}\times 6\times 16=48\ m\] \[{{S}_{y}}={{u}_{y}}t+\frac{1}{2}{{a}_{y}}{{t}^{2}}\Rightarrow {{S}_{y}}=\frac{1}{2}\times 8\times 16=64\ m\] \[S=\sqrt{S_{x}^{2}+S_{y}^{2}}=80m\]You need to login to perform this action.
