Question

A ping-pong ball weighs 2.5 x 10-2N. The ball isplaced inside a cup that sits on top of a vertical spring. If thespring is compressed 0.055 m and released, the maximum height abovethe compressed position that the ball reaches is 2.84 m. Neglectair resistance and determine the spring constant. I am coming up with an answer of 11 n/m. I am correct? A ping-pong ball weighs 2.5 x 10-2N. The ball isplaced inside a cup that sits on top of a vertical spring.

Explanation / Answer

ResponseDetails: we know that F = k * x or m * g = k * x or k = (m * g/x) m * g = 2.5 x 10-2N x = 0.055 m or k = (2.5 x 10-2/0.055) = 0.4545 N/m
