Okay thank you.

Wouldn't the wheel slide towards the right? Then friction would have to act towards the left.

Without friction, the wheel would just slip on the surface, but not really move.

I just realized I typed that wrong. The force is applied to the right and friction acts to the left.

So then friction has to be towards the left. The wheel rotates clockwise because the force is applied to the left and friction acts opposite to that applied force. Am I right?

How do I know which direction friction is if I don’t know the direction of motion?

I think we are supposed to assume that the wheel doesn't slip.

I tried to use the right hand rule to find torque but I’m not sure to go from there.

I figured it out can you delete the post please?

Which one?

The problem is based on a projectile-spring launcher. A ball is loaded into a tube that pushes back a spring and is then launched. The ball was launched straight horizontally not at an angle. I'm trying to find the work done on the ball by the spring. The info I have: Displacement of spring =...
