While an object is moving at a constant speed of 20m/s, a 5n forcé pushed the object to the left. at the same time a, 5n force is pushing the object to the right. what will the objects velocity be after 10 seconds

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 .
