Question

A toy car of mass 0.02 kg, gets into an elastic collision with a toy train mass 0.45 kg. If the train is at rest and the car is moving at 2.1 m/s initially. How fast is the train moving after the collision?

Answer #1

A toy car having mass
m = 1.20 kg
collides inelastically with a toy train of mass
M = 3.95 kg.
Before the collision, the toy train is moving in the positive
x-direction with a velocity of
Vi = 2.40 m/s
and the toy car is also moving in the positive
x-direction with a velocity of
vi = 4.55 m/s.
Immediately after the collision, the toy car is observed moving
in the positive x-direction with a velocity of 2.15
m/s....

A train car with mass m1 = 550 kg is moving to the
right with a speed of v1 = 8.5 m/s and collides with a
second train car. The two cars latch together during the collision
and then move off to the right at vf = 5.2 m/s.
What is the mass of the second train car? kg Submit 3) What is
the change in kinetic energy of the two train system during the
collision?

A 7.50 kg bowling ball moving at 4.00 m/s makes an elastic head
on collision with a 2.50 kg bowling pin initially at rest. Find the
velocity of the bowling pin after the collision.

Consider an elastic collision in one dimension that involves
objects of mass m1=2 kg and m2=11.3 kg. The
larger mass is initially at rest, and the smaller one has an
initial velocity of 16 m/s. Find the final velocities of the two
objects after the collision.

A 5.0-kg mass moving at 8.0 m/s collides head-on with a 3.0-kg
mass initially at rest If the collision is perfectly elastic, what
is the speed of the masses just after the collision? Is the kinetic
energy conserved?

In an elastic collision, a 480-kg bumper car collides directly
from behind with a second, identical bumper car that is traveling
in the same direction. The initial speed of the leading bumper car
is 4.5 m/s and that of the trailing car is 7.2 m/s.
Hint
Assuming that the mass of the drivers is much, much less than
that of the bumper cars, what are their final speeds?
The speed of the leading bumper car after collision
is m/s, and the...

A crash test dummy with a mass of 65-kg is in a moving car going at
20 m/s, until it crashes into a wall. If the applied force was
measured at 1,750 N, how long (in seconds) did the collision last?
2) Consider two hockey pucks on frictionless ice: Puck A with
a mass 1.10 kg, and Puck B with a mass of 0.60 kg.
Puck A is initially moving to the right at 1.75 m/s towards
puck B,...

Consider the inelastic collision of truck with a stationary car.
The truck has a mass of 10,000 kg. The car has a mass of 2000 kg.
If the truck comes into the collision at 16.3 m/s, how fast are
they going both going after the collision assuming they stick
together with the truck pushing the car?

A hockey puck of mass 0.550 kg is moving to the right with a
speed of 5.80 m/s and has a head-on collision with a 1.00 kg puck
initially at rest. Assume a perfectly elastic collision.
What is the speed of the lighter puck after the collision?
What is the speed of the heavier puck after the collision?

A 4.34-kg toy car with a speed of 4.13 m/s collides with a
stationary 1.00-kg car. After the collision, the cars are locked
together with a speed of 3.6 m/s. How much kinetic energy is lost
in this collision?
