Perfectly Elastic
This is only always conserved in a perfectly elastic collision
What is kinetic energy?
This happens in a 2 object explosion
What is the separation of two objects?
This happens to the objects in a perfectly inelastic collision
What is the objects sticking together after the collision?
Impulse is a change in this quantity
What is momentum?
This is always conserved in a closed system
What is momentum?
What is 0?
This is the general formula for momentum in explosions
(m1+m2)v1=m1v2+m2v3
The AP likes using this non-silly material to indicate perfectly inelastic collisions
What is putty?
This is the impulse formula with calculus
What is the integral of force with respect to time
Object 1 with velocity 2v and mass m collides with object 2 of -v and mass m, the resulting velocity of object 1 is 1v and the resulting velocity of mass 2 is -2v. This much kinetic energy is lost in the collision.
What is 0(J)?
Object 1 with mass m and velocity v(0) collides perfectly elastically with object 2, which has mass 4m and is at rest. What is the magnitude of the resulting velocity of object 1? Assume all objects are confined to the x-axis.
1/3v(0)
Lost energy can be converted into this type as a result of explosions (any type works)
What is (heat, sound, light, chemical, etc.)
The maximum amount of this energy is lost in a perfectly inelastic collision
What is kinetic energy?
The force exerted on an object is given by F=e^x. This is the impulse experienced by the object between t=0,3.
What is (e^3)-1 N-s?
A 300kg cannon shoots a 20kg cannonball, and the cannon immediately moves with a velocity of .05 m/s afterwards. Both objects are initially at rest. The cannonball collides perfectly inelastically with a 4kg (2mx2mx5m) sack of bread (initially at rest). This is the resulting momentum of the cannonball and bread combination.
What is 15 kg-m/s?
An rubber ball of mass (pi^2)kg with velocity v=(10*e)m/s collides perfectly elastically with a (13pi)kg wall at rest. The wall does not move. This is the resulting magnitude of the momentum of the rubber ball.
What is 268.28 kg*m/s?
A 1500kg launcher at rest shoots a 500kg missile at 300 m/s, at an angle of 30 degrees to the horizontal. What is the resulting velocity of the launcher? (Assume the laucher is free to move on a flat surface)
What is -86.6 m/s (left)?
Object 1 has velocity 𓆏 and mass 𓈳. Object 1 collides with object 2, which is at rest with mass 2𓈳, with the two objects sticking together afterwards. If 𓈳=2.4(kg) and 𓆏=4.1(m/s), this is the resulting velocity of the masses after the collision.
What is 1.367 m/s?
An object experiences an impulse of 300 N-s over a .003 second period. This is the total force acting on the object.
What is 100000 N?
You cannot find this quantity and momentum at the same time
What is position?
A totally inanimate and dead rubber chicken (that exists in all dimensions and realities)of mass .5m and velocity 2.2v collides perfectly elastically with a completely and utterly normal wall that cannot speak, and can move freely, without angering horrors beyond human comprehension, having mass 10m, with 13 orbiting electrons at a maximum radius of 14in. The wall is initially at rest. This is the resulting kinetic energy of the system.
What is (1.21m)(v^2)?
A 300kg cannon explodes into three equal pieces in midair, with one piece flying at 100 m/s at an angle of 60 degrees to the horizontal and the second flying at 50 m/s at an angle of 322 degrees. This is the velocity and angle of the last piece. (Use standard assumption and assume pieces are bound to the x-y axis)
What is 105.4 m/s at 212.04 degrees?
A 500kg eagle flying at 100 km/s (100000 m/s) crashes into a 50kg screen door at rest and sticks to it. The combined objects drive into a viscous substance which slows them at an acceleration of a=-3t m/s^2. This is how far the objects travel after hitting the screen door, and the time during this point. (Ignore relativistic effects) (Hint: use your GRAPHING calculator (GRAPHING GRAPHING GRAPHING))
What is 14920181m at 246.183 seconds?
An object experiences a force of 287-([t^3]/4) N-s over a 3.7 second interval. This is the total impulse over the interval acting on the object.
What is 1050.186 N-s?
This is a likely origin of denoting momentum with p
What is Hamilton's statement at a Royal Society lecture labelling q as position and p as momentum?
