Explanation / Answer

We will use kepler's second law which says that rv is constant.

where v is speed of asteroid at the point and r is the distance from planet.

hence velocity will decrease with increase in radius.

also for TE , we look at intersection point and compare velocity at that point. More velocity means more KE and hence TE, as PE is same
