Physics

This is a theoretical question, ignore the numbers.

A 205-kg log is pulled up and to the right on a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0 degrees with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.900, and the log has an acceleration up and to the right of magnitude 0.800 m/s2. Find the tension in the rope.

I do not need the math, but I just need to identify the number of forces on the log... I guessed 5 but it was wrong.

How many forces are there (0 to 7?)

Here are my 5 forces
1) Pull from the rope
2) Resistance from the pull from friction
3) Gravity
4) Accelerating of the log (f=ma)

  1. Oops, then I miscounted... then would my answer be correct if it was 4?

  2. Acceleration is not a force. The fourth force is the normal force the ramp exerts on the log.
