Question

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.

Answer #1

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.

2a) Mass 1 is moving at 6 m/s in the +x
direction and it collides in a perfectly
elastically with mass 2 of 2 kg
moving at 15 m/s in the -x direction. They
collide for 0.3 seconds, and the average
force on mass 1 is 148 N in the -x direction. What is
the mass of mass 1 in kg?
2b) Mass 1 is moving at 3 m/s in the +x
direction and it collides
inelastically with mass 2...

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...

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 of 5 kg is moving at 12 m/s in the +x direction and it
collides inelastically with a mass of 10 kg moving in the -x
direction. The collision takes places in 0.27 seconds and the
average force on the mass moving in the +x direction is 170 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.

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...

A mass of 3 kg is initially moving in the +x direction and
collides inelastically with a mass of 10 kg moving in the -x
direction at 2 m/s. After the collision, both masses move in the +x
direction at 4 m/s. How much kinetic energy is lost in the
collision in Joules? Answer is positive

3.) A mass is moving at 9 m/s in the +x direction and it
collides in a perfectly elastic collision with a mass of 4 kg
moving in the -x direction. The collision takes places in 0.23
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...
