object initially at rest explodes into three picces. Piece A has a mass of 5 kg, B has a mass of 3.0 kg, and C has a mass of 2.5 kg. After the explosion, A's velocity is (3.0 m/s)i + (2.0 m/s) j and B's velocity is (2.0 m/s)i - (3.0 m/s) j y at rest explodes into three pieces. Piece A has a mass of 5.0 a. What is C's velocity after the explosion? b. Calculate the change...

6. An explosion breaks an object initially at rest into two pieces, one of which has 3.0 times the mass of the other. If 7100 J of kinetic energy were released in the explosion, how much kinetic energy did the heavier piece acquire? Joules 7. A billiard ball is shot west at 2.20 m/s. A second, identical billiard ball is shot cast at 1.80 m/s. The balls has a glancing collision, not a head-on- collision, deflecting the second ball by...

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...
