Well I really don't know which eccuations are you talking about.

How should I do this I if Ii don't have the mass?

Homework Statement You are sliding downhill a slope of 10% (what angle is that?). Calculate how the starting velocity of 10 km/h changes within the first 120 s. After that you try to climb up an icy hill with 5% slope. Is that possible? Homework Equations Vf = Vi +At The Attempt at a Solution...

V = d/t then a = v/t I think I got it?

Can you please show me the formulas I'm suppose to be taking into account?

I'm at a loss again then, is average velocity the same as a constant velocity?

Thanks a lot! So I should assume that the final velocity is 0 and use the kinematic equation to get acceleration?

So that 0.7 can be taken as the distance?

Can you give me a hint? I know that I'm over looking something very basic but I can't seem to find what?

I know the Kinematic Equations and how they work.

I've been trying to study for my final and I can't seem to figure out how is this suppose to work. 1. Homework Statement A wall (m infinite, v=0) hits a car (m=2600 kg; v=142 km/h). The car becomes deformed and the crush zone (0.7 m) is compressed. Calculate the corresponding acceleration...
