When she hosts a garden party, Julie likes to launch bagels to her guests with a spring device that she has devised. She places one of her 200-g bagels against a horizontal spring mounted on her gazebo. The force constant of the spring is 300 N/m, and she compresses it 9 cm.

(a) Find the work done by Julie and the spring when Julie launches a bagel.

(b) If the released bagel leaves the spring at the spring's equilibrium position, find the speed of the bagel at that point.

(c) If the bagel launcher is 2.2 m above the grass, what is Julie’s horizontal range firing 200-g bagel?
