A block of mass 0.250 kg is placed on top of a light, vertical spring of force constant 5 000 N/m and pushed downward so that the spring is compressed by 0.100 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise?
The block of 4.5 kg is attached to a spring with spring constant k = -1.6 and extended to an initial displacement of 9 cm. It takes 20 s to make a full cycle. What is the displacement after 7s?
A 4.0 kg-block attached to a 20 N/m-spring constant spring moves on a frictionless horizontal surface, back and forth between -3.0 m and +3.0 m. What is the speed of the block when it is at -2.0 m, in m/s? Your answer needs to have 2 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.
A 50 g ice cube can slide without friction up and down a 30º slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 13.0 cm. The spring constant is 25 N/m. When the ice cube is released, what distance (in cm) will it travel up the slope above the release point before reversing direction? Use g = 10 N/kg. In your calculations, make sure you convert to consistent units (kg and meters).
