A student skates up a ramp that makes an angle with the horizontal. He/she starts (as shown in the figure) at the bottom of the ramp with speed and wants to turn around over a semicircular path of radius during which he/she reaches a maximum height (at point ) from the ground as shown in the figure. Assume that the energy loss is negligible and the force required for this turn at the highest point is provided by his/her weight only. Then ( is the acceleration due to gravity)

Starting at time from the origin with speed , a particle follows a two-dimensional trajectory in the plane so that its coordinates are related by the equation . The and components of its acceleration are denoted by and , respectively Then
1
implies that when the particle is at the origin,
2
implies at all times
3
at , the particle's velocity points in the -direction
4
implies that at , the angle between the particle's velocity and the axis is
