Leah watches a toy car move across a table at a constant speed. the car moves across the table in one direction and falls off the other side. leah decides to try another situation. she watches the car move across the table at a constant speed, then when it reaches the other side of the table, her friend joey pushes the car in the other direction. the car moves back to leah. based on leah's informal experiment, the car changes direction because of force, which happens when a. an unbalanced; leah watches the car b. an unbalanced; joey pushes the car c. a balanced; the car moves across the table d. a balanced; joey pushes the car

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
