Question

before: $p_1 + p_2 = -13$ kg m/s
assuming momentum is conserved,
what is $p_1$?
$p_1 = ?$ kg m/s
$p_2 = -4$ kg m/s
+9 kg m/s
+13 kg m/s
-9 kg m/s
-17 kg m/s

Explanation:

Step1: Apply conservation of momentum

$P_1 + P_2 = P'_1 + P'_2$

Step2: Rearrange to solve for $P'_1$

$P'_1 = (P_1 + P_2) - P'_2$

Step3: Substitute given values

$P'_1 = -13 - (-4)$

Step4: Calculate the final value

$P'_1 = -13 + 4 = -9$

Answer:

C. -9 kg m/s
