A) 11 m/s
B) 22 m/s
C) 33 m/s
D) 44 m/s
Correct Answer: B
Solution :
\[{{V}_{7}}={{V}_{5}}+\frac{3\pi }{8}\times 2\] To calculate V5 i.e. velocity at end of 5 sec. \[a={{\left( 25-{{t}^{2}} \right)}^{{}^{1}/{}_{2}}}\Rightarrow \frac{dv}{dt}={{\left( 25-{{t}^{2}} \right)}^{{}^{1}/{}_{2}}}\]You need to login to perform this action.
