To find the distance from the table that the puck lands after it falls off of the table.

But, you do know gravity, and when that quantity comes into effect, you use it.

You solve it symbollically.

So, the final velocity in the y-direction is 8.4m/s. Can anyone confirm this for me?

Nevermind.

What is s?

I do not think I have ever seen this formula. Could you explain exactly what the symbols represent, I mean except for a, which I assume to represent acceleration.

It tells me that the normal force - the force of gravity = m_car * a_y = 0, yes?

What is u?

But if all of the cars have the same mass, and the mass cancels out when you do the y-direction of the sum of the forces, will it not come out to be the same acceleration?

But the accelerations could not be the same for all three cars, could they?

So the forces on cars B and C are pointing in the same directions as the forces on car A?

Well, gravity goes straight down. My first instinct is to say that normal goes perpindicular, but perpindicular to what? So, maybe it is oposition to gravity, but I doubt it. And I am also not sure about friction, I know it goes in the opposite direction of the front of the car, but whether...

Sweet...now, how exactly would I begin to classify the forces on cars B and C as in either the x- or y-direction?

A rocket-powered hockey puck has a thrust of 1.20N and a total mass of 1.50kg. It is released from rest on a frictionless table, 3.20m from the edge of a 3.60m p. The front of the rocket is pointed directly toward the edge. I have found that the acceleration of the hockey puck in the...
