A point mass is moving at speed v, on a horizontal plane, until it reaches an incline. Immediately after just climbing up the incline, its speed remains at v, but its direction changes. How does this happen?
Q2: Now, I drop a point mass such that it falls vertically downward onto a fixed ramp.
Is only velocity parallel to the slope of the ramp preserved? I think this is because the ramp exerts an impulse on the ball such that the momentum perpendicular to the slope is removed.
