(Honors) A train is traveling up a 3.2 degree incline at a speed of 3.55 m/s when the last cart breaks free and Multiple r begins to coast. (A) Draw a FBD. (B) How long does it take for the last cart to come to rest? (C) How far did it go before it stopped momentarily? 7) You push a 25 kg wooden box across a wooden floor at a constant speed of 1 m/s, the coefficient of kinetic friction is mk=.2 .(A) Draw a FBD (B) How much force do you exert on the box? 8) (Honors) A baseball player slides into third base with an initial speed of 7.9 m/s. If the coefficient of kinetic friction between the player and the ground is .41, (A) Draw a FBD(B) how far does the player slide before coming to rest? 9) A string exerts a force of 58 N on a box at an angle of 34 degrees from the horizontal. The box has a mass of 4 kg and the coefficient of kinetic friction is .2. What is the acceleration of the box when the box is moving? 10) (Honors) A flatbed truck slowly tilts its bed upward to dispose a 95 kg crate. For small angles of tilt the crate stays put, but when the tilt angle exceeds 23.2* the crate begins to slide. What is the coefficient of static friction between the bed of the truck and the crate? 11) (Honors) A child goes down a playground slide that is inclined at an angle of 27.5 below the horizontal. Find the acceleration of the child given that the coefficient of kinetic friction is .415
