Using Impulse to Calculate Initial Height

Using Impulse to Calculate Initial Height (6:54)

A 66 g beanbag is dropped and stops upon impact with the ground. If the impulse measured during the collision is 0.33 N·s, from what height above the ground was the beanbag dropped? This is an AP Physics 1 Topic.
