A) 38.8 m
B) 58.8 m
C) 98.8 m
D) None of these
Correct Answer: B
Solution :
Taking vertical downward motion of the ball form point of projection to ground \[\operatorname{u}=-19.6m/s,\,\,a=9.8\,\,m/{{s}^{2}}\] \[t\,\,=\,\,6s\] \[\therefore \,\,\,\,\,\,\,\,s = ut+ \frac{1}{2}a{{t}^{2}}\] \[\therefore \,\,\,\,\,\,\,\,s = -19.6\times 6 +\frac{1}{2}\times 9.8\times {{6}^{2}}\] \[= \,\,58.8\,m\]
