(b) A 10 kg wooden block initially stationary is pulled by a force , F = 12.0 N over a distance of 4 m. Assume the motion happens on a frictionless surface. The force F then is released and the wooden block moves over a rough surface, r. Let the coefficient of the kinetic friction between the block and surface r as 0.40. Calculate: (i) The speed of the wooden block after moving through a distance of 4 m. (4 marks) (ii) The acceleration (or deceleration) when the block moves on surface r. (3 marks) (4 (iii) The distance traveled over the surface r before it stops. marks)
