The collision of two balls of equal mass takes place at the origin of co-ordinates. Before collision, the components of velocities are \(\left(v_{x}=50 \mathrm{~cm} / \mathrm{s}, v_{y}=0\right)\)and (vx = –40 cm/s and vy = 30 cm/s). The first balls comes to rest after collison. The velocity components (vx and vy respectively) of the second ball are :
- 10 cm/s and 30 cm/s
- 30 cm/s and 10 cm/s
- 5 cm/sand 15 cm/s
- 15 cm/sand 5 cm/s
Answer
(A) 10 cm/s and 30 cm/s
