Consider the track shown in the figure below. Section AB is a quadrant of a circle of radius r = 2.00 m and is frictionless. From B to C is a horizontal section 3.0 m long with a coefficient of kinetic friction μk = 0.250. The section CD under the spring is frictionless. A block of mass m = 1.00 kg is released from rest at A. After sliding on the track, the block compresses 0.200 m the spring. Determine (using conservation of energy): (a) the speed of the block at point B. (b) the thermal energy (internal energy) produced when the block slips from B to C. (c) the velocity of the block at point C. (d) the stiffness constant k for the spring.

How do you measure the mass of an astronaut in orbit? (You can't just use a scale!) For the 1973 - 1979 Skylab program (Skylab was a space station that predated the current International Space Station), NASA engineers designed a Body Mass Measuring Device (BMMD). This is essentially a chair of mass m mounted on a spring with a carefully measured spring constant ks = 605.6 N/m. (The other end of the spring is connected to the Skylab itself, which has a mass much larger than the astronaut or the chair, and so remains essentially fixed as the astronaut oscillates.) The period of oscillation of the empty chair is measured to be 0.90149 s. When an astronaut is sitting in the chair, the period is 2.12151 s. What is the astronaut's mass? Please describe your reasoning!
Question in pic.
A 2.0 kg breadbox on a frictionless incline of angle θ=40° is connected, by a cord that runs over a pulley, to a light spring of spring constant k = 133 N/kg as shown in the figure below. The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless. How far down the incline (in meters) from its point of release does the box slide before momentarily stopping (kinetic energy = zero at this point). Use g = 10 N/kg.
What is the spring constant of the spring as shown, in N/m? Use g = 10 m/s². Your answer needs to have 2 significant figures, including the negative sign in your answer if needed.

(Don't forget to convert units.) Hint: This is a projectile motion problem. Use time to fall t = srt(2*y/g).
