Conclusion (b) in Part 5 is a possible reason why temperatures has an effect on how fast water freezes. Refine your original question for this experiment. In other words, create a question for an experiment that
would prove or disprove conclusion (b)

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
