A) 0.1
B) 0.5
C) 1.0
D) 0.01
Correct Answer: A
Solution :
[a]\[{{\operatorname{V}}_{0y}}={{V}_{0}} sin \theta \], this component does not change \[{{v}_{0x}} = {{v}_{0}} cos\theta and u cos \theta \] For elastic collision relative velocity before collision is equal to relative velocity after collision along \[x-axis\] \[{{v}_{0}}\cos \,\theta -u\text{ }cos\text{ }\theta =u\text{ }cos\theta +{{v}_{x}}\] \[\operatorname{If}\,\,{{v}_{x}} cos\theta ={{v}_{0y}}Sin\theta \] By solving \[m=0.1\]You need to login to perform this action.
