Homework Statement
A particle of mass m=1kg moves counterclockwise in a horizontal circle of radius r=1m with uniform speed of 1 m/s. Determine the velocity, acceleration, total force and the component of the the total force on the particle in direction of its velocity as a function of the...
Are you referring to the a in the net horizontal force has to be 0 always in static case? Or both for vertical as well?
Horizontal: F cos θ - μn = 0
Vertical : -mg + F sin θ + n = 0
Solving the y equation gives n= F cos θ / μ
Homework Statement
You try to push a crate of weight M with a force F on a horizontal floor. The coefficient of static friction is μ and you exert the force F under an angle θ below the horizontal.
a) Determine the minimum value of F that will move the crate
b) Assume you have not...
