Two identical objects that can stick together, one at rest, the other moving towards it 3. A heavy object and a lighter one that would bounce from each other.

2020Q2: Please answer all parts in specific detail and explain each step with reasoning

huma The mass of the block depicted in the image is 1.08 kg. The spring has a spring constant of 78.1 N/m. The coefficient of static friction between the block and the floor is 0.594. Assume that the spring makes no contact with the floor and therefore friction only acts on the block. How far must the block and spring assembly be compressed to just barely overcome the force of static friction acting on the block? Report your result in meters.

Catcher pendulum in initial position Spring loaded gun A student completes the "Ballistic Pendulum" with different lab equipment and collects this data: M, Mass of Pendulum Arm: 255 grams L, Length of Pendulum Arm: 31.6 cm m, Mass of Ball: 44.7 grams , Angle: 24.6 degrees What is the speed of the ball BEFORE it collides (and sticks in) the pendulum arm? Give your answer to 3 significant figures (2 decimal places in this case).

A pendulum is released and swings until it stops. If it passes through an arc of  25 inches the first pass, and if on each successive pass it travels 2/5 the distance of the preceding pass, how far will it travel before stopping? To solve this problem fully, respond the following questions a) Write the distance traveled in expanded form b) Write the distance traveled in sigma notation c)  How far will it travel before stopping?

Lastly, from part 1, pendulum lab, we clearly would need to set the bob swinging from some angle along with considering other parameters (set up) for our experiment. With that, lets think about some follow-up questions. a. Does the period of a pendulum depend on starting angle? why or why not? b. Does the period of pendulum depend on mass? why or why not? c. Is the ratio of length to period always a guarantee for a value of g? explain. d. Using the predictive model that was obtained for both f(L) and T(L), determine the period at lengths 35 cm, 40 cm, and 45 cm. Be sure to take exp(f(L)) for the exact period. e. What is the general conclusion of the period obtained for other lengths?

Star Energy UNIT 4 The diagram above shows a conceptual model of a spherical star that generates and emits light energy. Here are the assumptions we will make about the star: · Each cubic centimeter of the star's interior generates 3x10 watts of power. · Each square centimeter of the star's surface shines 6,000 watts of power into space. (a) Suppose the star has a radius of about 7×10° cm. How much power would the interior of the star generate? How much power would the star's surface shine into space? Which quantity is greater? (b) Suppose the star has a radius of about 5×10" cm. How much power would the interior of the star generate? How much power would the star's surface shine into space? Which quantity is greater? (c) Life on Earth depends on our Sun maintaining equilibrium, neither growing nor shrinking. Likewise, in this conceptual model of the star, if the star is too small, then the number of watts leaving the surface will exceed the number of watts generated in the interior,…
