In the impulse approximation the external forces acting during a collision are neglected as they are small in compare to the interacting force between objects
2nd option is correct
Add Answer to:
In the impulse approximation, the true impulse is approximated by a rectangular pulse O the external...

Learning Goal: To understand
the relationship between force, impulse, and momentum. The effect
of a net force ΣF⃗ acting on an object is related both to the force
and to the total time the force acts on the object. The physical
quantity impulse J⃗ is a measure of both these effects. For a
constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse
is a vector pointing in the same direction as the force vector. The
units...

Full Solution Problem for Chapter 06 (FS06)-Using Generalized Momentum-Impulse equation driving 20 m/s when it sees a deer (at rest in the road). The driver of the car hits the brakes, but it's too late- he hits the deer. The deer sticks to the car (sorry, deerl) and they skid forward as the car br has a mass of 500 kg and the deer has a mass between the car's tires and the road is 0.&. (Friction is much smaller...

The system consists of the two objects and the only forces affecting the motion are the internal forces betwoen them during collision. ANALYZE (A) Determine the velocity after collision Because no external force acts, the colligion does not change the total momentum of the system of two particles. We set the total momentum before collision to the total momentum afterward: myVsm (m + m)v The final...

Indicate whether each item is true or false. If an item is false, please correct it so that it is true. Speed is a scalar quantity. Work and energy are vector quantities. Objects that are not moving cannot have any work done to them. Pressure is uniform throughout a fluid, regardless of depth Density of a material changes as the temperature of the material changes. Solids are always more dense than liquids. Liquids are always more dense than gases Falling...
