A student uses two identical balls to perform an investigation. The student throws ball A with a horizontal velocity from a height of 10 meters. At the same time, another student drops ball B from the same height without horizontal velocity. Neglecting air resistance, which best describes the results

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 .
