AP Physics C: Mechanics LAST, FIRST Name: Quiz 6: N2L and N3L (friction, ramps) Period: Standard | Question 2&3 4 Total B2b - (x2.0) Newton's Second Law (FBDs and equations) NA B2c - (x3.0) Objects with specific Acceleration (F - a) NA B2d - (x2.0) Coefficient of Friction B3a - (x2.0) Force Pairs NA NA A factory worker is pulling a 50-kg crate up a ramp towards her, She does this by pulling on a rope attached to the crate while she remains stationary (the distance between the rope and the worker is decreasing). The rope is parallel to the ramp and at the moment the crate is accelerating up the ramp at 0.1 m/s?. at Fo Of = D. S 1) Draw and label free body diagrams of the crate and the worker. Indicate which type(s) of friction are present, if any, Indicate which forces, if any, form a Newton's Third Law force pair. 2) Express N2L for the crate, in terms of the forces shown on its free-body diagram, Incorporate what is known about the crate's motion into your response. 3) Express N2L for the worker, in terms of the forces shown on her free-body diagram. Incorporate what is known about the worker's motion into your response. 4) The coefficients for static and kinetic friction between the ramp and the crate are 0.4 and 0.2, respectively. Determine the magnitude and direction of the force exerted by the worker onto the crate. 0 . 1
