PLS ANSWERR THIS QUESTION FOR ME !!

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 .

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?

The current through a 10 ohm resistor is 1.2 amperes.what is the potential difference across the resistor?
