Mass m1=25.7 kg is on a horizontal surface, connected to mass m2= 5.10 kg by a light string as shown. The pulley has negligible mass and no friction. A force of 222.5 N acts on m1 at an angle of 30.9o.The coefficient of kinetic friction between m1 and the surface is 0.233. Determine the upward acceleration of m2.
help please?
I'm guessing is a hanging mass.
let T = magnitude of the tension in the string between and .
F = magnitude of the applied force on
N = magnitude of the normal force on by the horizontal surface
net force on ...
net force on ...
where ...
and will experience the same magnitude of acceleration ... solve the system of equations for "a".
