F ma friction
Web2024 F= maExam A 4 6.A packing crate with mass m= 115 kg is slid up a 5:00 m long ramp which makes an angle of 20:0 with respect to the horizontal by an applied force of F= 1:00 103 N directed parallel to the ramp’s incline. A frictional force of magnitude f= 4:00 102 N resists the motion. If the crate starts from rest, what is WebFriction is the force that resists motion when two surfaces come into contact with each other. If the two surfaces do not move with respect to one another it is called static …
