A 0.250 kg block is placed on a vertical spring k 5.0 x, Ask an Expert

Academics

Q. A piston, A has a diameter of 0.64 cm. A second piston, B has a diameter of 3.9 cm. determine the force F necessary to support the 500N weights in the absence of friction.

Q. A 0.250 kg block is placed on a vertical spring (k = 5.0 x 10^3 N/m) and pushed downward, compressing the spring 0.10 m. As the block is free, it leaves the spring and continues to travel upward. What height above the point of release would the block reach if air resistance is negligible?
