i did the lab today n have 2 questions. 1. Newton's original law was written in term of momentum and time. Show how than can be rearranged to what we know as Newton's second law of motion F=ma 2. What circumstances would lead to a situation where linear momentum is not conserved ?

There are (one can say) three coequal theories of motion for a single particle: Newton's second law, stating that the total force on an object causes its acceleration; the work- kinetic energy theorem, stating that the total work on an object causes its change in kinetic energy; and the impulse-momentum theorem, stating that the total impulse on an object causes its change in momentum. In this problem, you compare predictions of the three theories in one particular case. A 3.40-kg...

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...

Using the alternate form of Newton's second law, compute the force (in N) needed to accelerate a 1,020 kg car from 0 to 15 m/s in 17 s. The change in momentum is the car's momentum when traveling 15 m/s minus its momentum when going 0 m/s. (Enter the magnitude.)

Preliminaries (5 pt): Momentum and Impulse • Newton's third law can also be phrased in terms of momentum: for any closed system of objects, the total momentum remains Note that momentum can be exchanged between two objects in a closed system. However, the change in momentum for one object must be to change in momentum of the other object. • Fill in the appropriate...
