- You want the final speed at the bottom of your roller coaster hill to be 25 m/s. What is the height (h) of the hill to achieve this? Use g = 9.8 m/s2When we think about air resistance, we can definitely predict or expect that the air resistance forces heavily rely on speed. Explain what exactly do you look forward to when it comes to that reliance, is it F ∝ v^2? is it F ∝ v? is it F ∝ 1v^2 or something completely different? Elaborate on why you predict this relationship4. A constant force of 35N acts on a 10 kg box. The direction of the force is to the left. If the box is originally at rest, what willi be its velocity after 5s? Indicate the magnitude and direction of the velocity.
