Question

Show Basic Equations First, before plugging in numbers. Include units in all answers. If there is more than one part, separate the work for Part (a) and the other parts clearly by labels. Draw accurate free-body as appropriate for each problem, with vectors drawn in correct directions and labeled. Box all answers.

3. An object of mass 6.8 kg is attached to a spring of force constant 1,720 N/m. The object is set into simple
harmonic motion, with an initial velocity of vo=4.1 m/s and at the same time an initial displacement of
X, = 0.11 m.
a) Calculate the maximum velocity the object has during its motion.
b) Calculate the amplitude of the oscillation.

A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. The cabinet starts from rest. What is the final kinetic energy of the cabinet at the end of the ramp, in Joules? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Common speech often uses the term "work" to refer to situations where, according to the physics definition of work, there is no actual work done. Find an example of this and explain why the non-physics public considers this work and what a proper physics response would be to this error. You must use ordinary language in an attempt to clarify what is happening do not rely on trigonometry or scalar dot products in you answer . Some examples you could consider include a person pushing on a wall and the wall not moving, a person doing a "bench seatisometric exercise where they squat against a wall, the moon being pulled by gravity as it orbits the earth, etc.
In a popular new mini hockey game, players use small launchers with springs to move a 5 gram puck. Each spring has a spring constant of 150 N/m and can be compressed up to 5 cm. Solve for the maximum speed with which the puck can be launched. Show all of the work necessary to reach your solution. Start with general equations and explain what you are doing and why you did what you did. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable. I just need help with question #2 please
