Sergei tees off on a stationary hockey puck using his most powerful slap shot. If he can exert a force of 250 N on the 500 gram

puck for a time of 0.1 seconds, what velocity will he give to it, and how far will the puck move in the time it is on his stick?

Answer: velocity = 50m/s

Distance moved=5m

Explanation:

Using the formula Ft=Mv i.e impulse= momentum

Where F= force ,t= time, M= mass, v = velocity

In this case we need to find v,

F,t,M are all given in the question.

Therefore, substituting the values we have

250N×0.1s=0.5kg×v. Mass=500g= 0.5kg

v=25/0.5= 50m/s

The distance the puck will move when it is on his stick.

D= Velocity × time

D=50m/s × 0.1s

D=5m

Goodluck...

The diagram shows a charge moving into an electric field. The charge will most likely leave the electric field near which letter
Simora [160]

you haven't attached the diagram, but i assume that this diagram is what you were talking about

Answer:

near Y

Explanation:

the electric field lines goes from a positive charge to a negative charge. This means that a positive charge would move in the same direction of the field lines, while a negative charge would move in the opposite direction of the field lines. the field lines are created from +vely charged plate to -vely charged plate so the negative charged particles moves towards the lower plate which is positively charged, and opposite to the direction of field lines.
