Question 4 (1 point) When working with two-dimensional motion, choose the direction of to be a positive direction. north and east Saved I A/
Question 5 (1 point) ✓ Saved If you are moving upward in an elevator at constant speed, the normal force would the force of gravity. be Question 6 (1 point) If you are accelerating N upwards in an elevator, the normal force would be the force of gravity. A
Question 8 (1 point) Tension force over a pulley. P throughout a string that changes direction
Question 9 (1 point) In the force system diagram pictured below, the factor that would NOT influence the amount of kinetic friction is LL E Z+ N V Fa Saved μK F₁
Question 10 (1 point) If the strength of the frictional force is equal to the applied force and oppositely directed, and assuming that all other forces may be ignored, the object must be at rest or I applied force N Question 11 (1 point) ✔ Saved The force of kinetic friction always acts in a direction exactly opposite to the direction of A
Question 12 (1 point) If all other forces can be ignored and the strength of the frictional force is greater than the applied force and oppositely directed, the object must be A
