Hope this helps
Answer:
tA=tB
tB=(sA-dA)/vA watch it below
Explanation:
the spatio for A is sA=vA*tA+dA
the spatio for B is sB=vB*tB
the meeting point will happen at: tA=tB
so, sA=vA*tB+dA
tB=sB/vB
yields:
sA=vA*(sB/vB)+dA
sA-dA=vA*(sB/vB)
sB=(sA-dA)*vB/vA
then
tB=((sA-dA)*vB/vA)/vB
tB=(sA-dA)/vA
Answer:
-0.912 m/s
Explanation:
When the package is thrown out, momentum is conserved. The total momentum after is the same as the total momentum before, which is 0, since the boat was initially at rest.
where are the mass of the child, the boat and the package, respectively. are the velocity of the package and the boat after throwing.
This type of energy is called non mechanical energy so the answer is C
