A body of mass 50 kg explodes and splits into three pieces. The first piece has a mass of 10 kg and a velocity of [-3,2] m/s, th
e second piece has a mass of 18 kg and a velocity of [5,-4]m/s. What is the velocity of the third piece?
1 answer:
Step-by-step explanation:
From the conversation of angular momentum
Initial momentum=final momentum
Here,
Since body is initially resting, it's momentum must be zero.
Let v be velocity of third piece. Then
0= 10(-3i+2j) + 18(5i-4j) + 22v
Solving this we get,
v= 4/22(15i+13j).

Add numbers with the same amount of variables
-x^2 + (-7x^2) = -8x^2
– 28x (+ 14x )= -14x
7 (+ 8) = 15
-18x² - 14x + 15 is your answer
hope this helps
