Question

A 42-g firecracker is at rest at the origin when it explodes
into three pieces. The first, with mass 21 g, moves along the x
axls at 29 m/s . The second, with mass 12 , moves along they axis
at 35 m/s . a) What is the mass of third plece ? b) What is the
magnitude of the velocity of the third piece? c) Whal angle does
the third plece make with x axis ?

Please show work.

A tank, at rest at the origin of an x-y coordinate system,
explodes into three pieces. Just after the explosion, one piece,
mass of m, moves with the speed v in the negative x- direction, and
a second piece, with mass m/2, moves with a speed vd at
an angle of 30 degrees (down or -yaxis) with respect to the +x
axis. The third piece with mass m/2 moves with speed vu
at an angle (up or +y axis) of...

A vessel at rest explodes, breaking into three pieces.
Two pieces, having equal mass, fly off perpendicular to one another
with the same speed of 45m/s. One goes along the negative x-axis
and the other along the negative y-axis. The third piece has three
times the mass of each other piece.
What are the direction and magnitude of its velocity immediately
after the explosion?
1)What is the angle with respect to the x-axis?
2)What is the magnitude of its velocity?

An object with total mass mtotal = 16.4 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 = 18° above the –x axis
with a speed of v1 = 26 m/s. A second piece with mass m2 = 5.2 kg
moves down and to the right an angle of θ2 = 23° to the right of
the -y axis...

an object at rest explodes into three pieces of equal mass. one
move east at 20m/s a second moves southeast at 30m/s. what is the
velocity of the thrid piece?
ANS: V3= 46.4 m/s

Problem 9: A watermelon is blown
into three pieces by a large firecracker. Two pieces of equal mass
m fly away perpendicular to one another, one in the x
direction another in the y direction. Both of these pieces fly away
with a speed of V = 22 m/s. The third piece has three
times the mass of the other two pieces.
Randomized VariablesV = 22 m/s
33% Part (a) Write an expression for the speed
of the larger piece,...

A bomb at rest, with mass m,
explodes into three unequal pieces. 1/3 of the mass moves north
with a speed of 48.0 m/s. ½ the mass moves 58° west of north with a
speed of 27.0 m/s. Find the speed and direction of the last
piece.

1.0-kg grenade explodes into four pieces, all moving parallel to
the ground. The first piece of mass 0.20 kg moves east at 24 m/s.
The second piece of mass 0.30 kg flies north at 18 m/s. A third
piece of mass 0.25 kg is directed west at 30 m/s. What is the
velocity of the fourth piece?

a
firecracker in a coconut blows the coconut into three pieces. two
pieces of equal mass fly off south and west, perpendicular to each
orher, at 18 m/s. the third piece has twice the mass as the other
two. what is the speed of the third piece? what is the direction of
the third piece?

A firecracker in a coconut blows the coconut
into three pieces. Two pieces of equal mass fly off south and west,
perpendicular to each other, at 15m/s
. The third piece has twice the mass as the other
two.
What is the speed of the third
piece?
