\( 1 . \) Click the tools icon to open the tool menu. Notice this activity has two horizontal rulers, one in \( \mathrm{cm} \) and one in \( \mathrm{N} \). The ruler is \( \mathrm{N} \) is calibrated to measure the force the spring exerts. Briefly explain how you could design a ruler to measure the force a spring exerts. Hint: The force that the spring exerts depends on how much it stretches from its initial resting state. Look for a clear reference point on the spring to measure. Score: \( 0 / 2 \) 2. When the spring is fully stretched, how does the force of the spring on the cart compare to the force of the turbine on the cart? Explain your reasoning. Hint: If you'd like to include a free-body diagram, you can click the picture icon ? to add a photo or image. 5. A student thinks the acceleration might be constant but isn't sure. They collect data and make the following motion graphs: postion vs time velocty v time What can they conclude about the motion of the glider from these graphs? Explain your reasoning.
