Question

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 at a speed of v2 = 20.6 m/s.

5)

What is the magnitude of the velocity of the center of mass of the pieces after the collision?

Answer #1

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
= 26.1 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 with total mass mtotal = 15.5 kg is sitting at rest
when it explodes into three pieces. One piece with mass m1 = 4.5 kg
moves up and to the left at an angle of θ1 = 22° above the –x axis
with a speed of v1 = 26.3 m/s. A second piece with mass m2 = 5.3 kg
moves down and to the right an angle of θ2 = 27° to the right of
the -y axis...

An object with total mass mtotal = 17.4 kg is sitting at rest
when it explodes into three pieces. One piece with mass m1 = 4.9 kg
moves up and to the left at an angle of θ1 = 21° above the –x axis
with a speed of v1 = 25.9 m/s. A second piece with mass m2 = 5.1 kg
moves down and to the right an angle of θ2 = 26° to the right of
the -y axis...

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...

A
bomb explodes into 3 pieces. First piece m1=1kg, moves at v1=2m/s
at 30 degree to the horizontal m2=2kg moves at v2=1.5m/s to the
right and m3=3kg moves at v3=4m/s at 45 degree below the
horizontal. What was the bomb's initial velocity(magnitude and
direction)?

A bomb at rest explodes into three fragments. Two of these
fragments with mass m1 = 2 kg, and m2 = 1 kg respectively, travel
in left direction; the other fragment with mass m3 = 3 kg travels
in opposite direction. If the velocities of fragments 1 and 2 are
v1 = 5 m/s and v2 = 2 m/s respectively, find the velocity of
fragment 3.

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
axis at 29 m/s. The second, with mass 12 g, 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) What angle does
the third piece 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...

An unstable nucleus of mass 2.1 ? 10?26 kg, initially
at rest at the origin of a coordinate system, disintegrates into
three particles. One particle, having a mass of
m1 = 4.6 ? 10?27 kg, moves in the
positive y-direction with speed v1 =
6.1 ? 106 m/s. Another particle, of mass
m2 = 8.5 ? 10?27 kg, moves in the
positive x-direction with speed v2 =
4.5 ? 106 m/s. Find the magnitude and direction of the
velocity of...

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.
