A 59 g arrow is shot straight up into the air with a speed of 25 m/s. It reaches a maximum height of 30.8878 m. Find the initial kinetic energy. The acceleration of gravity is 9.8 m/s 2. Answer in units of J.

A block of mass 200 grams is connected to a light, horizontal spring with a spring constant k = 5 N/m. It is free to oscillate on a frictionless surface, and we'll also neglect air resistance so you don't have to worry about decaying.

Materials with a density__water will float in water

A 0.5 kg ball is thrown horizontally towards a wall with a speed of 10 m/s. The initial velocity is chosen to be the positive x - direction for this question.
