You are pushing a 10-kg wagon with a 5-kg pumpkin on a horizontal frictionless surface as shown. The surface between the pumpkin and the wagon is roughened so that there is no slipping between the two. You are applying a 30-N push to the wagon as suggested in the figure. a. What is the acceleration of the wagon-pumpkin system? b. What is the force of static friction between the pumpkin and wagon? c. What is the minimum coefficient of static friction necessary to keep the pumpkin from slipping on the wagon?
