Velocity of the ball A after collision with the ball B as shown in the figure is (Assume perfectly inelastic and head on collision)

Question

Velocity of the ball A after collision with the ball B as shown in the figure is (Assume perfectly inelastic and head on collision) (A) (3/7) m / s (B) (5/7) m / s (C) (1/7) m / s (D) Zero

Using momentum conservation 10-10=2 mv 1 ⇒ v1=0

Q. Velocity of the ball A after collision with the ball B as shown in the figure is (Assume perfectly inelastic and head on collision)

$\frac{3}{7} m / s$

$\frac{5}{7} m / s$

$\frac{1}{7} m / s$

Zero

Using momentum conservation
$10 - 10 = 2 m v^{1}$
$\Rightarrow v^{1} = 0$

73​m/s

75​m/s

71​m/s

Zero

Using momentum conservation 10−10=2mv1 ⇒v1=0

$\frac{3}{7} m / s$

$\frac{5}{7} m / s$

$\frac{1}{7} m / s$

Using momentum conservation
$10 - 10 = 2 m v^{1}$
$\Rightarrow v^{1} = 0$
