Consider two force vectors in the xy-horizontal plane. suppose a force of 12.7 n pointing along the +x-axis is added to a second force of 18.1 n directed at 30 degrees to the +x-axis , also in the horizontal plane. find the resultant vector for this sum. magnitude direction degrees above the +x-axis in the horizontal plane

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 .
