I don't really know how to approach this problem but let me give the question first... A package is dropped from a plane which is flying with a constant horizontal velocity of V_a=150 ft/s. Determine the normal and tangential components of acceleration and the radius of curvature of the path of...

Ok, I found the velocity of the block at the top of the incline. Which kinematic equation and in which direction should i start?

Would the distance I use for W=Fd in this equation be the horizontal or vertical distance. Because if its the vertical distance then i can solve for v but if its the horizontal then i have 2 variables in my equation.

I figure that If i can find the velocity of the block at the top of the hill then the rest of the problem is cake with kinematics

Well, I first tried to use work and kinetic friction to find the horizontal distance of the hill however once I reached to the end of my calculations I figured that what I was doing found the the entire distance that the block travels. So then I tried using the conservation of energy to find the...

The spring in the figure has a spring constant of 1100 N/m. It is compressed 16.0 cm, then launches a 200g block. The horizontal surface is frictionless, but the block's coefficient of kinetic friction on the incline is 0.180. What distance D does the block sail through the air? heres a...
