Froghopper insects have a typical mass of around 12.5 mg and can jump to a height of 42.3 cm. the takeoff velocity is achieved as the insect flexes its legs over a distance of approximately 2.00 mm. assume that the jump is vertical and that the froghopper undergoes constant acceleration while its feet are in contact with the ground. ignore air resistance. what is the acceleration of the insect during the time of the jump (before it leaves the ground)?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
