Homework Statement
1.13 * 10^5 km/h^2 to km/h * s
1.13 * 10^5 km/h^2 to m/s^2
Homework Equations
None
The Attempt at a Solution
I'm not sure how to convert these because of the h^2 that's really screwing me up.
Homework Statement
A 27 lb meteorite struck a car, leaving a 27 cm deep in the trunk. If the meteorite stuck the car with a 520 m/s what was the magnitude of deceleration assuming it to be constant
Homework Equations
None
The Attempt at a Solution
I have to be honest I have no clue...
Ok then for A taking direction into account since west is - then displacement, velocity and acceleration would all be - wouldn't they?
For C acceleration would be + and displacement + because your position is changing.
Is that correct?
Sorry I'm not familar with the summation formula. I solved for V in the second equation and got V = .6sinx.
I substituted that into the second equation and got sin = 0, 180 or 360 but then the 2nd equation doesn't check out. I know I'm doing it wrong somehow just not sure how
Well to be honest I'm really not sure. This is my first week of Physics (AP) and I've been really confused about the class so far.
For A and C which parts were wrong?
For A:
Displacement + because as you move away from 0 your displacement from the original increases doesn't it?
Velocity...

I've been really stumped by this one from my math class. It's a two variable trig. question with two equations. I believe there simultaneous but I'm not sure
3 = 1.2(cosx) + v(cos30)
0 = 1.2(sinx) - v(sin30)
Solve for the values of x & v
Please explain how you got your answer or...
