Sometime later she comes to a sheer cliff, where she pauses to admire the view. Seizing his chance for revenge, the badger pushes Jessica from behind, applying a force of 100 N in the direction of motion over a distance of 1 m to the edge of the cliff. Jessica has a mass of 75 kg and was initially at rest. Assume friction is negligible and the cliff is 10 m high, and answer the following questions. a) How much work did the badger do on Jessica? b) What is Jessica's speed just as she leaves the top of the cliff? c) What is Jessica's speed at the bottom of the cliff? d) Assuming her initial velocity upon leaving the cliff is entirely horizontal, how far from the base of the cliff will Jessica land? ail your workA crate is being pushed across a flat, level floor with a force of 1000 N. The friction on the crate is 400 N. The crate has a mass of 250 kg. a) What is the weight of the crate? b) What is the net force acting on the crate? c) What is the crate's acceleration? d) If the crate begins at rest, how far will it have gone after 10 seconds?
