SATHEE: Rotational Motion Question 113

Rotational Motion Question 113

Question: Two objects that are moving along an $x y$ -plane on a frictionless floor collide. Assume that they form a closed, isolated system. The following table gives some of the momentum components (in kilogram meters per second) before and after the collision. Before collision After collision


Before collision	After collision
Object	$p_{x}$	$p_{Y}$	$p_{x}$	$p_{Y}$
A	-4	5	3	A
B	b	-2	4	2

What are the missing values (a, b)?

Options:

A) 10, 11

B) 1, 11

C) 5, 7

D) 6, 4

Show Answer

Answer:

Correct Answer: B

Solution:

[b]

$p_{x}$ (before collision) = $p_{x}$

(after collision) $\Rightarrow - 4 + b = 3 + 4 \Rightarrow b = 11$

$P_{Y}$ (before collision)= $P_{Y}$

(after collision) $5 - 2 = a + 2 \Rightarrow a = 1$
