Question

A 26 kg body is moving through space in the positive direction of an x axis with a speed of 160 m/s when, due to an internal explosion, it breaks into three parts. One part, with a mass of 10 kg, moves away from the point of explosion with a speed of 76 m/s in the positive y direction. A second part, with a mass of 8.9 kg, moves in the negative x direction with a speed of 650 m/s. What are the (a) x-component and (b) y-component of the velocity of the third part? (c) How much energy is released in the explosion? Ignore effects due to the gravitational force.

Answer #1

A 15 kg body is moving through space in the positive direction
of an x axis with a speed of 110 m/s when, due to an
internal explosion, it breaks into three parts. One part, with a
mass of 7.9 kg, moves away from the point of explosion with a speed
of 150 m/s in the positive y direction. A second part,
with a mass of 4.0 kg, moves in the negative x direction
with a speed of 530 m/s....

away from the point of explosion with a speed of 424 m/s along the
positive y axis. A second fragment, whose mass is 4.5 kg, moves
away from the point of explosion with a speed of 335 m/s along the
negative x...

A 41.0-kg body is moving in the direction of the positive x axis
with a speed of 283 m/s when, owing to an internal explosion, it
breaks into three pieces. One part, whose mass is 5.0 kg, moves
away from the point of explosion with a speed of 408 m/s along the
positive y axis. A second fragment, whose mass is 2.5 kg, moves
away from the point of explosion with a speed of 316 m/s along the
negative x...

a 30 kg object is moving through space in the +x direction with
a speed of 20 m/s when, due to an internal explosion, it breaks
into three parts. A 15kg parrt moves away from the explosion with a
speed of 10 m/s in the +y direction, a 6kg part moves in the -x
direction with a speed of 5m/s. what is the magnitude of the
velocity of the remaining part?

A body of mass 11.0 kg is traveling at 4.3 m/s
along the positive x-axis with no external force acting. At a
certain instant an internal explosion occurs, splitting the body
into two chunks of 5.5 kg mass each. The explosion gives
the chunks an additional 16 J of kinetic energy. Neither
chunk leaves the line of original motion. Determine the speed and
direction of motion of each of the chunks after the explosion.

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest
at the origin of a coordinate system, disintegrates into three
particles. One particle, having a mass of
m1 = 2.6 ✕ 10−27 kg,
moves in the positive y-direction with speed
v1 = 5.4 ✕ 106 m/s.
Another particle, of mass
m2 = 8.0 ✕ 10−27 kg,
moves in the positive x-direction with speed
v2 = 3.4 ✕ 106 m/s.
Find the magnitude and direction of the velocity of...
