A) \[\frac{52}{3}\,m/s\] upward
B) \[\frac{52}{3}\,m/s\] downward
C) \[3\text{ }m/s\]
D) \[9.8\text{ }m/s\]
Correct Answer: A
Solution :
\[\text{S=ut+}\frac{\text{1}}{\text{2}}\text{a}{{\text{t}}^{\text{2}}}\] \[-76=4\times 6-\frac{1}{2}\times 10\times {{\left( 6 \right)}^{2}}\Rightarrow u=\frac{52}{3}\text{ m/s}\]Not Available
