6. Suppose you want the little stick figure to push the crate along the horizontal section and then,once it is part way up the incline, the crate comes to rest. With the ramp at 56.5°, what would µs need to be to get the crate to remain stationary on the incline? Hint: will the force of static friction be pointing up the ramp or down the ramp? After you calculate things, run the simulation with this value for the static friction coefficient. What happened? Did the crate's motion stop completely on the incline? If so, why? If not, what could be a possible explanation?
