A curious duck hops on a floating wooden plank in a river . The mass of the duck is 1.4 kg while that of the plank is 5 kg. Assume that there is no friction between the water & plank . The coefficients o) static & kinetic frictions are Me = 04 and Mp = 0.3 respectively between the duck's feet and the plank . ' Find the acceleration of both the duck and the plank if a gust of wind applies horizontal force on the plank . Assume they both start from rest. a ) magnitude of force F = 10 N b) magnitude of force F = 26N Take g= 9.8 m/s 2 ) F
