1. The Problem: A bomb at rest explodes, breaking into three pieces. Two of the pieces hace equal mass and fly off at 80° of each other with a speed of 100m/s. The tird piece has three times the mass of the other pieces. What is the magnitude and the direction of the third piece?
2. Homework Equations
potential energy equations for the x and y axis
is have
px: m0v0 = m1v1 +m2v2 +(3)m3v3
py: m0v0 = m1v1 +m2v2 +(3)m3v3
3. The Attempt at a Solution
This is what i have so far, my confusion is that i was not given any direction and am not sure what i am suppose to put in for theta for m1 and m2 so that i can find v3 and theta3? thank you for any help in advance!
px: 0 = m1v1cos(theta) +m2v2cos(theta) +(3)m3v3cos(theta)
py: 0 = m1v1sin(theta) +m2v2sin(theta) +(3)m3v3sin(theta)
px: 0 = m1(100)cos(theta) + m2(100)cos(theta) +(3)m3v3cos(theta)
py: 0 = m1(100)sin(theta) + m2(100)sin(theta) +(3)m3v3sin(theta)
