- In a TV commercial pickup truck B of mass mB lifts large crate A of mass mA toawrd the top of a cliff by means of a cable and a frictionless pulley. The truck uses constant thrust force F to do the job and accerates forward starting from rest, There are no friction forces except the thrust force F. a) Determine a symbolic formula for the magnitude of the acceration experienced by the crate. The final formula should not include the unknown tension force. b) explain whether the cable tension must be greater than, equal to, or less than the crate weight. c) for mass mA= 1500 kg, mb=2800 kg, and F=18,000N, how far will the crate rise in the first 3.5 s of motion?arrow_forward4.
