A vessel at rest at the origin of an xy coordinate system explodes into three pieces. Just after the explosion, one piece, of mass m, moves with velocity (-32 m/s) i Overscript ̂ EndScripts and a second piece, also of mass m, moves with velocity (-32 m/s) j Overscript ̂ EndScripts. The third piece has mass 3m. Just after the explosion, what are the (a) magnitude and (b) direction (as an angle relative to the +x axis) of the velocity of the third piece?
conservation of linear momentum
m1 = m; v1 = -32 m/s i
m2 = m; v2 = -32 m/s j
m3 = 3m = v3 = ??
mvo = m1v1 + m2v2 + m3v3
initaally vessel at rest
0 = m(-32 i ) + m(-32 j) + 3mv3
v3 = 32/3 i + 32/3 j
magnitude
|V3| = sqrt(vx^2+ vy^2)
|V3| = 15.085 m/s
direction = 45 degree counterclockwise from +x direction

A bomb at rest at the origin of an xy-coordinate system explodes into three pieces. Just after the explosion, one piece, of mass 2 kg, moves with a velocity of 43 m/s in the negative x-direction, and a second piece, also of mass 2 kg, moves with a velocity of 30 m/s in the negative y-direction. The third piece has a mass of 7 kg. What is the initial momentum of the bomb before the explosion? What is the x-component...
An object, hanging at rest, explodes, breaking into three pieces. Two pieces, one with twice the mass of the other, fly off perpendicular to one another with the same speed of 31.4 m/sec. The third piece has three times the mass of the lightest piece. Find the magnitude and direction of its velocity immediately after the explosion. (I defined this problem with the mass m going in the +x direction, the mass 2m going in the +y direction, and the...
An object located at the origin and having mass M explodes into 3 pieces having masses M/4, M/8, and 5M/8. The pieces scatter on a horizontal, frictionless xy-plane. The piece with mass M/4 flies away with velocity 7.2 m/s at 37 degrees above the x - axis. The piece with mass M/8 has velocity 4.5 m/s directed at an angle of 45 degrees above the -x axis. a) What are the velocity components of the 3rd piece? b)Describe the motion...
An object with total mass mtotal = 16.2 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.7 kg moves up and to the left at an angle of θ1 = 23° above the –x axis with a speed of v1 = 25.3 m/s. A second piece with mass m2 = 5.1 kg moves down and to the right, an angle of θ2 = 28° to the right of the -y axis...
QUESTION 10 1. An object of mass m, initially at rest at the origin, explodes into two pieces. The first piece, 87.5 percent of the mass, moves along the negative x-axis at 1.32 m/s. Find the speed, in m/s, of the other piece right after the explosion. NOTE: You do not need to know mass m!
A 10kg mass initially at rest explodes into three pieces. A 4.5kg piece goes north at 20 m/s and a 2.0kg piece moves eastward at 60 m.s. A) Determine the magnitude and direction of the velocity of the third piece. B) Compare the final Kinetic Energy of the system to the original kinetic energy of the system.
A 400 kg bomb sitting at rest on a table explodes into three pieces. A 150 kg piece moves off to the East with a velocity of 150 m/s. A 100 kg piece moves off with a velocity of 200 m/s. What is the velocity of the third piece?
An object with total mass mtotal = 6.4 kg is sitting at rest when it explodes into two pieces. The two pieces, after the explosion, have masses of m and 3m. During the explosion, the pieces are given a total energy of E = 45 J. What is the speed of the smaller piece after the collision? What is the speed of the larger piece after the collision? If the explosion lasted for a time t = 0.029 s, what...
