Question

Two masses collide in an **elastic** collision,
with the following initial values:

*m*_{1}= 2 kg*m*_{2}= 3 kg*v*_{01}= 5 m/s*v*_{02}= -4 m/s

Use the conservation rules, and algebra, what is the final
velocity of mass 1, *v*_{f1} in m/s?

Answer #1

In the lab frame two masses, m1=10 kg and
m2=6 kg collide elastically in one dimension with
initial velocities v1=17 m/s and v2=3
m/s.
Calculate the kinetic energy of mass mn after the
collision, where n=2.
Enter responses using three significant digits.

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.

Consider a perfectly inelastic collision, where
two objects collide with each other, and stick together. The net
external force on the system is 0.
m1 = 2 kg
m2 = 3 kg
v01 = 5 m/s
v02 = -4 m/s
a) What is their final velocity, after the collision, in m/s?
Make sure you get the correct sign.
b) How much kinetic energy was lost in the collision, in
Joules?

Two-car, 2-D collision. Two cars with masses
m1 = 1200 kg and m2 = 1500 kg are approaching an
intersection. Car 1 has a velocity v1 = 15.0 m/s towards
the east and car 2 has a velocity v2 = 20.0 m/s towards
the north. The two cars reach the intersection at the same time and
collide and lock bumpers and after the collision travel as a single
wreckage.

Two objects collide in a totally inelastic collision. Just
before the collision,
the objects have the following masses and velocities:
M1 = 4.5 kg, v1 = 1.5 m/s @ 140o. M2 = 1.5 kg, v2 = 1 m/s @
180o.
a) Find the velocity of the object after the collision.
b) How much kinetic energy was lost in the collision.
