Question

Quizplus · Accepted Answer

The potential energy stored in a compressed spring is given by the formula $ \frac{1}{2}kx^2 $, where $ k $ is the spring constant and $ x $ is the compression distance. Here, $ k = 300 \, \text{N/m} $ and $ x = 9.0 \, \text{cm} = 0.09 \, \text{m} $. Plugging these values into the formula gives $ \frac{1}{2} \times 300 \times (0.09)^2 = 1.215 \, \text{J} $, which rounds to 1.2 J.
