3. Shown is the block m=5 kg. Coefficients of static and kinetic friction are 0.3 and 0.1, respectively. a) What magnitude of force F will set the block in motion? b) After system starts moving, what is the acceleration of the block? Use 2nd Newton's Law. Be careful when calculating normal force, it's not mg! 20°
