    Finding the velocity at the top of a loop

    I did experience that my result for my own equation was false, since the result apparently shows squareroot of a negative number. I do not have a starting height, as the car moves into the loop, and isn't projected into the loop from a hill or something.

    Finding the velocity at the top of a loop

    Thank you so much :) Been trying to solve it in a way more complex way, as I thought that the approach with √g*r would only lead to the speed of the car as a Whole (Average speed in the loop). Sorry if I was being abit misleading with the intro, but you answered it perfectly :)

    Finding the velocity at the top of a loop

    Is that the speed itself at the top of the loop, or the average speed when it goes around the loop?

    Finding the velocity at the top of a loop

    Hey Guys. I've been spending the last 1½ week trying to figure this out on my own, but I just can't find the answer. A car (toy car) weights at about 0,062 Kg, and enters the loop at the speed of 0,60 m/s. The radius of the loop is 0,2011 m. Find the speed at the top of the loop (Not...
