Hi can someone me im really confused on these tree we decrease the amount of force applied to an object, and all other factors remain the same, the amount of work completed will (2 points) decrease. increase. increase, then decrease. not change. 13. if we increase the amount of work, and all other factors remain the same, the amount of power will (2 points) decrease. remain the same. increase. decrease, then increase. 14. imagine that you pushed a box, applying a force of 60 newtons, over a distance of 4 meters. how much work have you done? (2 points) 15 joules 56 joules 64 joules 240 joules

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.
