Ajet is flying at 450 mph due south for a total of 300 miles. there is a wind blowing at 100 mph from the southwest, so the pilot angles the plane's velocity to travel a direct path between the two locations. calculate the time that it takes for a round trip.

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 .
