A) 18.75m
B) 15m
C) 22.5m
D) 20.25m
Correct Answer: A
Solution :
Speed of ball before collision is \[\frac{\pi }{4}\]m/s Since, collision is perfectly inelastic (e = 0), so the ball will not bounce. It will move along the plane with velocity \[\frac{\pi }{3}\]m/s \[\frac{\pi }{2}\] Maximum height attained by the ball \[f(x)={{\log }_{5}}(25-{{x}^{2}})\] \[2x-y+z+3=0,\] \[r=(\hat{i}+\hat{j})+\lambda (\hat{i}+2\hat{j}-\hat{k})\]You need to login to perform this action.
