My exam is in an hour, so quick replies are dearly needed! http://www.ph.qmul.ac.uk/phy116/Exams/Mid%20Term%20Test%202006%20Answers.pdf [Broken] Question 3)a I would have said the force exerted by the RAMP on the MASS is mgcos30, not mg as my lecturer has said (and it's the same in every paper). What am I not seeing here? The only thing I can think of is due to the axis of where F is. Thanks!
