1.Two balls of mass 5 kg each moving in opposite directions with
equal speed say 10 m/s collide head on with each other. Predict the
outcome of the collision assuming it to be
Two automobiles, each of mass 500 kg, are moving at
the same speed, 10 m/s, when they collide and stick together. In
what direction and at what speed does the wreckage move (a) if one
car was driving north and one south; (b) if one car was driving
north and one east
thank you!!!
Two particles approach each
other with equal and opposite speed v. The mass of one particle is
m, and the mass of the other particle is nm, where n is just a
unitless number. Snapshots of the system before, during, and after
the elastic collision are shown above. After the collision the
first particle moves in the exact opposite direction with speed
2.40v, and the speed of the second particle is unknown. What is the
value of n?
Two projectiles with 50kg mass each are launched in opposite
directions towards each other, both at an angle of 30 degrees off
the horizontal. They both have the same initial velocity of 75m/s
and they are separated by a distance of 200m.
a.) What is their combined initial kinetic energy?
b.) Right before they collide, how high off the ground are
they?
c.) What is their total momentum here? (both directions)
d.) When they collide they stick together and lost...
1. A toy car of mass 2.0 kg moving to the right with a speed of
8.0 m/s collides perfectly inelastically with another toy car of
mass 3.0 kg that is moving to the left with a speed of 2.0 m/s.

A ball, mass m1 = 0.1 kg, is moving upwards with a speed of 10
m/s when it collides inelastically with a cup, mass m2 = 0.9 kg,
that is initially at rest. After the collision the system
(ball+cup) moves straight upwards without rotating. This collision
occurs on Earth, and the local gravitational field points down with
g = 9.8 m/s2 .
(a) What is the momentum of the system before the collision?
Write your final answers and neatly show...
1. A muon and an antimuon are moving in opposite directions with
velocities of -0.6 c and 0.6 c, respectively. When they collide,
they can annihilate each other and turn into two photons. Both muon
and antimuon have a mass of 105.66 MeV/c2. What is the total energy
before the collision?
2. What is the energy of each photon?
3. What is the wavelength of each photon?
8) 3 kg mass moving with 10 m/s in the x-direction hits a 5 kg
mass at rest. After the collision 3 kg is deflected by 30 degree
while the 5 kg is deflected by 45 degrees. a) Draw a diagram for
the initial and final motion including the directions of the
velocities b) Find the final velocities of each mass c) Determine
if the collision is elastic or not. d) Qualitatively, show the
direction of the impulse (or the...
1- Block 1 (mass 2.0 kg) is moving to right at speed of 5.0 m/s.
It collides with block 2 (mass 3.0 kg) that is moving to the right
at speed of 3.0 m/s.
a) What is the speed of the blocks if the collision is
completely inelastic? How much kinetic energy is lost? (3.8 m/s,
2.4 J)
b) What is the final speed of the blocks if the collision is
elastic? (v1 = 2.6 m/s, v2 = 4.6 m/s)...
A softball of mass 0.220 kg that is moving with a speed of 8.0
m/s (in the positive direction) collides head-on and elastically
with another ball initially at rest. Afterward the incoming
softball bounces backward with a speed of 6.4 m/s.
(a) Calculate the velocity of the target ball after the
collision.
(b) Calculate the mass of the target ball
A truck with a mass of 1350 kg and moving with a speed of 12.0
m/s rear-ends a 821-kg car stopped at an intersection. The
collision is approximately elastic since the car is in neutral, the
brakes are off, the metal bumpers line up well and do not get
damaged. Find the speed of both vehicles after the collision.
