A block with mass 18.6 kg is placed on an inclined plane with slopeangle 21.1^\circ and is connected to a second hanging block thathas mass 14.8 kg by a cord passing over a small, frictionlesspulley. The coefficient of static friction is 0.47 and thecoefficient of kinetic friction is 0.34.
What is the normal force on m_1?
If the incliuned slope is frictionless, what is the acceleration ofthe 2 masses? Use up the incline as your + x direction.
What is the tension in the cord in this case?
Assume friction is down the incline (we actually need to look atthe sign of acceleration in part a to be sure). If friction is downthe incline and the 2 blocks are not moving, what is the value offriction?
What is the maximum static friction?
