So, taking a different approach--I need to find all forces acting on the block, so if force P=800 in a horizontal direction (incline is 30), then its x and y components are 800N*cos(30), and 800Nsin(30). ANd if its weight force is mg=980N, then its x and y components are 980N*cos(30) and...
Thank you for that tip, denverdoc! I am trying to figure out a way to use eq3, but I don't have the friction force, that's what I am solving for, but I have velocities and a mass, which is why I chose to use eq4
Wow! that was fast! Thank you!
Is the applied force P=800 N? For the accelerating force do I use the F=ma? Do I use F=m ((v2)^2-(v1)^2)/(2d)? so I get 730 for my friction force?? So confused!
Work done by a friction force, block moving up a ramp--question
Homework Statement
100kg block moves up on a rough surface, at an incline of 30 degrees, a constant force P=800 N is applied horizontally moving the block a distance of 3 M up the ramp in a time interval of 2 seconds, v1=0.8...
