    Roller coaster loop cart velocity

    in an amusement park ride a cart of mass 300kg and carring four passangers each of mass 60kg is dropped from a vertical height of 120m alonga path that leads into a loop-the-loop machine of radius 30m. The cart then enters a straight stretch from A to C where friction brings it to rest after a...

    Height of a Ball on a Moving Wedge: How Does the Angle Affect the Result?

    well that was sort of my train of thought as well. the ball will exert a force onto the wedge thus making both move. we know that v'2 (that is the new velocity of the wedge with mass M) = (2M/m+M) * v1 (that is the original velocity of the ball) but I am confused because isn't the angle a...

    Height of a Ball on a Moving Wedge: How Does the Angle Affect the Result?

    Homework Statement a ball with mass m and velocity v is moving up a wedge of mass M. What height does the ball reach if: a) the ramp is fixed on the table b) the ramp is able to move on a frictionless surface Homework Equations mgh (1/2)mv(squared) The Attempt at a Solution for...
