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...
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...

A spacecraft at rest in deep space explodes into three pieces! One piece is going exactly “north” while a second is going exactly “west”. Which way might a third piece be going? Group of answer choices All of these are possible. Exactly “south” Exactly “south-east” A third piece could be stationary Exactly “east”
A mass M=4.5kg is on a horizontal, frictionless surface, and is initially at rest. It is subject to a position dependent force F =k( )'i. If k=49.4N, y=2.1, the mass is initially at Fi=1.4mi, what is the final velocity as M starts from rest and moves along the x-axis to a final position if =4.7mi? Answer in ". Answer: The correct answer is: 29.0 Try another question like this one
6. An explosion breaks an object initially at rest into two pieces, one of which has 3.0 times the mass of the other. If 7100 J of kinetic energy were released in the explosion, how much kinetic energy did the heavier piece acquire? Joules 7. A billiard ball is shot west at 2.20 m/s. A second, identical billiard ball is shot cast at 1.80 m/s. The balls has a glancing collision, not a head-on- collision, deflecting the second ball by...
What is the velocity of the third piece? A cherry bomb explodes into three pieces of equal mass. One piece has an initial velocity of 11m/s x. Another piece has an initial velocity of 8.0m/s x - 4.0m/s y.
10.9 A radioactive nucleus (mass = 1.70*10-26 kg) is at rest. It suddenly decays (explodes) into three pieces. One piece has mass mi = 5.00*10-27 kg and is found to be moving along the +y axis with a speed of 6.00* 10 m/s. A second piece with mass m2 = 8.40*10-27 kg moves along the +x axis with a speed of 4.00* 10° m/s. Assuming the mass is held constant, find the velocity of the third and final piece that...
