Late tests will be penalized. you may use your text and your notes(including homework and quizzes), but no other resources. answer every question. show your work. answers with no work receive no credit. circle numerical answers and give them to three significant digits. make sure your answers have correct units and that directions are clearly indicated for vectors. each question is worth 5 points, for 80 points total. a 300-g block of wood is placed on a level table, 80.0 cm from the edge. a string runs horizontally from the block to a pulley at the edge of the table. the string runs over the pulley and down to a 50.0 g hanger that hangs 50.0 cm above the floor. the system is released from rest and the hanger falls to the floor. the frictional force between the block of wood and the table is 0.250 n 1. draw a free body diagram of the block of wood just as it starts to move. be sure to list the objects and interactions draw a free body diagram of the hanger just as it starts to move. be sure to list the objects and interactions determine the tension in the string determine the acceleration of the hanger what is the speed of the block of wood when the hanger hits the floor? what is the acceleration of the block of wood after the hanger hits the floor? ift 0 is when the block is released, at what time does the block of wood reach the edge of the table? 2. 5. 6. 7. 8. f the mass of the block were doubled, how would this situation be different? be as 9. if instead the table were frictionless, how would the situation (with the 300 g block) be 10. if the table were frictionless, how would the situation be different if you doubled the detailed as possible different? be as detailed as possible. mass of the block? compare it to both the small-mass, no-friction case and to the doubled-mass, with-friction case a 100-kg crate needs to be pushed up a 2.00-m long ramp inclined at 5.00. i push it horizontally with a force of 150 n, and it does not move. i push harder, and when i push horizontally with a force of 200 n the crate moves with constant acceleration, takin go from the bottom to the top 11. draw a free body diagram of the crate when it is halfway up the ramp. be sure to list g 3.00 s to the objects and interactions. 12. determine the acceleration of the crate as it moves up the ramp 13. determine the net force on the crate when it is halfway up the ramp. 14. determine the magnitudes of all the forces on the crate when it is halfway up the 15. determine the value of the coefficient of kinetic friction between the crate and the 16. if i had stopped pushing part way up, would the crate have stayed put or would it have ramp ramp slid back down? explain your reasoning.
