In 1987. X-ray diffraction was used to determine that the thermal expansion of the protein metmyoglobin causes an increase of protein diameter by 1% after an increase in temperature from - 240 degrees * C to 20^ * C . What is the estimated VOLUME expansion coefficient, for this protein

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
