Really great stuff, thanks a lot.

Hey there guys I just have a question to ask some of you. Given the occurrence of time dilation being related to an objects state of motion I have an interesting thought. This is a very general question, my teacher only briefly covered this topic in class as it's not part of our course but it...

I got -35m/s as my velocity though

Very helpful, thank you.

Homework Statement In coming to a stop a car leaves skid marks 92m long on the highway. Assuming a decceleration of 7.00 m/s^2 , estimate the SPEED of the car just before braking. I have a question though, is my approach ok? You can see my confusion in various parts of my procedures below...

Yes! Thanks

Homework Statement I'd just like someone to see if I answered correctly. I'm having a bit of difficulty grasping the vagueness of the displacement in these questions I've been getting in my textbook. From what I gather the displacement is relative to the vector points, (the two x points in...

I have another question. My projectile starts at point 0,5 I am given this formula to solve the range of the projectile if y isn't equal to 0 I'm fine with it until the end, it says y0, why y0? Does it just mean insert the value of y that the projectile starts at?

You're right, thanks a lot!

Projectile Motion Question Homework Statement A cannon fires a projectile Velocity = 40 m/s The angle of the cannon= 35 degrees solve for Vx= V*cos(angle) and Vy=V*sin(angle) I am having a problem understand this concept relative to what the screenshot below shows...

You're right it does :). Thanks a lot, I got a real headache because of that.

Homework Statement f(x)=6x^2+9x-6 Where does this function intersect the x-axis (i.e. what are the roots or zeroes of f(x))? Solve by factoring using the Box Method. When I use the method that is shown on this website http://www.purplemath.com/modules/factquad2.htm for this...

That the domain is limited and does not include all real numbers for the function. I guess it sets a domain limit?

Homework Statement f(x)=(x-3)^2 -1 for x ≥3 Homework Equations The Attempt at a Solution I am having difficulty grasping the concept of changing the greater than or equal to part of the equation above to it's inverse form. If for x it says x≥3 then how would that statement be...
