Two parallel paths m apart run east-west through the woods. brooke jogs east on one path at 66 km/h, while jamail walks west on the otherpath at 77 km/h. if they pass each other at time t=0t=0 , how far apart are they 44 s later, and how fast is the distance between them changing at that moment?

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 .
