A 6490 kg helicopter accelerates upward at 0.57 m/s2 while lifting a 1190 kg frame at a construction site. What force does the cable exert on the helicopter?

The mass of the helicopter is of no consequence. The upward acceleration combined with earth's acceleration due to gravity is 0.57+9.81 = 10.38 m/s²
Multiply this by the mass of the frame to get the force (in Newtons)

we don't need the mass of the helicopter
Fnet = ma
Fnet is the sum of forces, in this case, Fweight and Tension are Fnet
Tension - Fweight = ma
Tension - (1190*9.8) = 1190 * .57
Tension - 11,662 = 678.3
Tension = 12,340.3N

..(9.81 - 0.57) x 1190 = 10,995.6 N
