5) A 20 kg wagon is pulled along the level ground by a rope inclined 30 degrees above the horizontal. (A) Draw a FBD of the wagon (friction is negligible) (B) How large is the pulling force is the wagon accelerates of .4 m/s?? (C) What is the normal force of the wagon? 6) A baseball player slides into third base with an initial speed of 5.5 m/s. If the coefficient of kinetic friction between the player and the ground is .41, how far does the player slide before coming to rest? B) Draw a FBD 7) An elevator containing 3 passengers (with a mass of 72kg 84 kg and 35 kg) has a mass combined of 1030 kg . The cable attached to the elevator exerts an upward force of 9800 N. What is the acceleration with the direction of the elevator at this instance
