Abox with a mass of 42.5 kg is pushed with a horizontal force of 150 n. the box moves at a constant speed across a level, rough plane a distant of 5.35 m. what’s is the work done (in j) by the 150 n force ?

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 .
