show all the work, used equations, and steps that you have used
A block of mass m1 = 10.0 Kg rests on a surface inclined at theta=30degree to horizontal. It is connected by a lightweight cord, which passes over a massless and frictionless pulley, to a second block of mass m2=8 Kg, as shown in the figure. The coefficient of static friction is mu s = 0.4 and that of kinetic friction is mu k = 0.3. It is found that m1 moves up along the plane and m2 moves vertically downward. What is the magnitude of the normal force on m1? What is the magnitude of the frictional force on m1? Find the acceleration of this two-block system.Explanation / Answer
use mgcost to find N, umgcost to find Ff, and netforce/total mass is acceleration so:
The normal force is 84.87 N, the frictional force is 25.46 N, and the acceleration is .218 m/s^2.
