What is the velocity of the truck after collision?
What is the velocity of the truck after collision?
5.0 m/s.
The truck’s velocity immediately after the collision is 5.0 m/s. As predicted, the truck has lost momentum (slowed down) and the car has gained momentum.
How do you solve an inelastic equation?
In physics, an inelastic collision occurs, when the maximum amount of kinetic energy of a colliding objects/system is lost….
- V= Final velocity.
- M1= mass of the first object in kgs.
- M2= mas of the second object in kgs.
- V1= initial velocity of the first object in m/s.
- V2= initial velocity of the second object in m/s.
What happens in an inelastic collision?
What is an inelastic collision? An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else.
What is a collision in physics?
In physics, a collision takes place when particles, aggregates of particles, or solid bodies move toward each other and come near enough to interact and exert a mutual influence.
How do you calculate the elasticity of a collision?
The elastic collision (k=1) is collision A. The inelastic collision (k = 0.5 in this case) is collision B. The completely inelastic collision (k = 0) is collision C….Collisions and Elasticity.
| Type of Collision | Description | Elasticity |
|---|---|---|
| Completely inelastic | Kinetic energy is smaller, and the objects stick together, after the collision. | k = 0 |
What is the velocity of the truck immediately after the collision?
To determine v (the velocity of the truck), the sum of the individual after-collision momentum of the two objects is set equal to the total momentum. The following equation results: Using algebra skills, it can be shown that v = 5.0 m/s. The truck’s velocity immediately after the collision is 5.0 m/s.
What is an extreme example of an inelastic collision?
To simplify matters, we will consider any collisions in which the two colliding objects stick together and move with the same post-collision speed to be an extreme example of an inelastic collision. Now we will consider the analysis of a collision in which the two objects do not stick together.
How do you determine the post collision velocity of an ice-bound person?
If it can be assumed that the effect of friction between the person and the ice is negligible, then the collision has occurred in an isolated system. Momentum should be conserved and the post-collision velocity ( v) can be determined using a momentum table as shown below.
What is the momentum of the medicine ball after the collision?
Since momentum is conserved, the total momentum after the collision is equal to the total momentum before the collision. Finally, the expressions 60 kg • v and 15 kg • v were used for the after-collision momentum of the person and the medicine ball.
