Example questions Sad ball Наpрy ball 1. Students are given two spherical balls made of different materials, but of identical mass and diameter to experiment with. Each ball is dropped from an initial height, ho. The "sad ball" comes to rest without visibly bouncing when it strikes the tabletop. The "happy ball" bounces up to a final height h, where h < ho- A fellow student wants to use one of the balls in a carnival game where cups are knocked over by a thrown ball. Which ball should they use, happy or sad? In a clear, coherent, paragraph-length response that may also contain figures and/or equations, explain what physics principles explain why the happy ball bounces higher off of the tabletop and explain which ball makes the better choice as a projectile in the carnival game.

4. You are riding the Detonator at Worlds of Fun. It's a ride where you get accelerated straight up and down several times. Google it if that's a confusing description. How fast does the ride need to accelerate you upward at the beginning of the ride in order to make you feel twice as heavy as you normally do? (your apparent weight is twice your actual weight) I b. How fast does the ride need to drop when you are at the top so that you just barely leave your seat? Hint: What is the magnitude of the normal force when you barely lose contact with the seat?

Constants | Periodic Table Two children are trying to shoot a marble of mass m into a small box using a spring-loaded gun that is fixed on a table and shoots horizontally from the edge of the table. (Figure 1)The edge of the table is a height H above the top of the box (the height of which is negligibly small), and the center of the box is a distance d from the edge of the table. The spring has a spring constant k. The first child compresses the spring a distance z, and finds that the marble falls short of its target by a horizontal distance di2. Part A By what distance, z2, should the second child compress the spring so that the marble lands in the middle of the box? (Assume that height of the box is negligible, so that there is no chance that the marble wilIl hit the side of the box before it lands in the bottom.) Express the distance in terms of m, k, g, H. and d. • View Available Hint(s) ? Hνα ΑΣφ I2 = Submit Part B Complete previous part(s) Next > Provide Feedback 1 of 1 Figure…

ACTIVITY 3 Problem Solving Gravitational Potential Energy and Elastic Potential Energy Energy is the ability to produce changes in matter. It has two states, the kinetic energy and potential energy. Kinetics energy has 3 forms, vibrational, rotational, and translational, While potential energy has 3 types, gravitational, chemical, and elastic potential energy. Gravitational PE is the energy stored because of its height and elastic PE is the energy stored in elastic materials as the result of their stretching or compressing. nga Read, analyze, and solve the following problems using the GUFSA template.
