I'm a little confused. In the y direction, the force due to gravity is the only force? And in the x direction, F = mv^2/r. So where would the angle come into play?

But would the seat still exert 700 N upward? I mean, would I just plug in the numbers into the equation for the second part?

So while in circular motion, you aren't pushing down on the seat with 700 N so you are lifted up?

so if the force were less than the original Fc required for circular motion, the ball would move in an elliptical orbit, but sort of inward? and regarding the first question, is it possible to calculate the angle that the string is "down", if i had mass, radius, and angular velocity? F = m R...

1. You're driving down the road at 8 m/s and go over a speed bump. When you go over the bump, you feel lifted from your seat. Explain why. I assumed it was because of inertia, but I'm not sure. You weigh 700 N. If it is approximated that the speed bump is shaped like an arc of a circle...

so an object will only move in a circular path if the force is equal to or greater than mv^2/r?

Just gravity?

1. Why is it that when you swing a ball around your head, the string or rope attached to the ball is always tilted down a little? That is, the rope isn't parallel to the floor, it is at a bit of angle at down. 2. The ball will continue to move in a circular path if the total force is...
