inelastically* with mass 2 of

**Please note that part A and part B have different
values.**

Answer #1

Mass 1 is moving at 3 m/s in the +x direction and it collides
inelastically with mass 2 of 16 kg moving at 13 m/s in the + x
direction. 138 Joules of KE is lost in this collision. What is the
average force on mass 1 if the collision takes place in 0.3
seconds? Answer in Newtons.

3) Mass 1 is moving at 2 m/s in the +x direction and it collides
inelastically with mass 2 of 17 kg moving at 13 m/s in the + x
direction. 120 Joules of KE is lost in this collision. What is the
average force on mass 1 if the collision takes place in 0.2
seconds? Answer in Newtons.

Mass 1 is moving at 2 m/s in the +x direction and it collides
inelastically with mass 2 of 19 kg moving at 14 m/s in the + x
direction. 132 Joules of KE is lost in this collision. What is the
average force on mass 1 if the collision takes place in 0.2
seconds? Answer in Newtons. The answer is 110 but how do I solve
it.

Q1) Mass 1 is moving at 2 m/s in the +x direction and it
collides inelastically with mass 2 of 17 kg moving at 11 m/s in the
+ x direction. 122 Joules of KE is lost in this collision. What is
the average force on mass 1 if the collision takes place in 0.1
seconds? Answer in Newtons.
Q2) A disk is initially spinning at 18 counter-clockwise. After
5 seconds, it is spinning clockwise and a piece of dust...

i)A mass of 3 kg is moving at 4 m/s in the +x direction which
collides inelastically with a mass (mass 2) of 8 kg. After the
collision, the masses are moving at 4 m/s in the +x direction. What
is the initial velocity of mass 2 in m/s? If in the negative x
direction, include a negative sign.
ii) A mass of 4 kg is moving at 6 m/s in the +x direction which
collides inelastically with a mass...

2) Mass 1 is moving at 7 m/s in the +x direction and it collides
in a perfectly elastically with mass 2 of 3 kg moving at 14 in the
-x direction. They collide for 0.2 seconds, and the average force
on mass 1 is 150 N in the -x direction. What is the mass of mass 1
in kg?

A mass of 4 kg is moving at 11 m/s in the +x direction and it
collides inelastically with a mass of 6 kg moving in the -x
direction. The collision takes places in 0.40 seconds and the
average force on the mass moving in the +x direction is 217 Newtons
in the -x direction. How much total kinetic energy is lost in the
collision in Joules? Answer is a positive number since I'm asking
how much is lost.

A mass of 5 kg is moving at 14 m/s in the +x direction and it
collides inelastically with a mass of 7 kg moving in the -x
direction. The collision takes places in 0.38 seconds and the
average force on the mass moving in the +x direction is 232 Newtons
in the -x direction. How much total kinetic energy is lost in the
collision in Joules? Answer is a positive number since I'm asking
how much is lost.

A mass is moving at 6 m/s in the +x direction and it collides in
a perfectly elastic collision with a mass of 5 kg moving in the -x
direction. The collision takes places in 0.25 seconds and after the
collision the mass that was moving in the +x direction is moving in
the -x direction at 6 m/s and the mass that was moving in the -x
direction is moving in the +x direction at 13 m/s. What is...

A mass is moving at 7 m/s in the +x direction and it collides in
a perfectly elastic collision with a mass of 2 kg moving in the -x
direction. The collision takes places in 0.19 seconds and after the
collision the mass that was moving in the +x direction is moving in
the -x direction at 9 m/s and the mass that was moving in the -x
direction is moving in the +x direction at 15 m/s. What is...
