Are all the forces on the helicopter balanced?
What is the magnitude of the net force on the helicopter?
What is the strength of the horizontal thrust component?
What is the strength of the thrust?

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.
