3. net force=ma
applied force-frictionforce=ma
so if a is zero, then friction force=?
4. appied force-frictionforce=ma
solve for friction force.
I NEED ANSWERS AND HOW YOU GOT IT~!!
3. If you use a horizontal force of 30.0 N to slide a 12.0-kg wooden crate across a floor at a constant velocity, what is the coefficient of kinetic friction between the crate and the floor?
4. A force of 4.0N is large enough to overcome the friction between a 5.0-kg block and a horizontal surface and accelerate the block at 6.0m/s2
A. How large is the friction force?
B. What is the coefficient of friction?
