momentum
The equation used to solve for impulse
What is Force times time?
An Elastic collision is one that conserves this
What is kinetic energy?
A truck with the mass of 1200kg is traveling at a velocity of 12m/s. Calculate the momentum of the Truck?
What is 14,400 Kg*m/s
This is the variable used for impulse
What is J?
completely inelastic collision
A .5kg baseball moving 30m/s is hit at 20m/s. What is the change in momentum of the ball?
25 Kg*m/s
This is caused by an impulse
What is the change of momuntum?
If a 500kg car moving 30m/s hits and sticks to a stationary 1000kg Dumpster they move off at this velocity.
what is 10m/s?
This is the variable used for momentum
What is P?
This impulse result from a force of 6t^2-2t N, acting over 2 seconds.
What is 12 N*s?
A 70kg running back running 8m/s hits and bounces directly back off of a 100kg defensive end running at him at 2m/s. The running back is moving forward at 1m/s after the collision, this is the velocity of the defensive end.
What is 2.9m/s?
This is what force =, when Newton's second law is written in terms of momentum instead of mass and acceleration.
What is dP/dt
This is how to determine the impulse from a force v. time graph.
What is calculate the area?
1This equation can be used instead of
1/2m1v12+1/2m2v22=1/2m1v1`2+1/2m2v2`2
for elastic collisions.
