Question

22. A 2000 kg truck is used to pul a stranded 60 kg hiker up out of a canyon. One end of a rope is attached to the rear end of the truck The rope extends horzontally behind the truck and passes over an "ideal" frictioniess puley The hiker hangs on to the other end of the rope. The truck and the hiker both accelerate at a rate of 0.500mf s as shown in the figure. Assume that the rope has negigible weight, and that air resistance is negligible a (0.500m 1/s^2) 300 A. Oraw a complete and fully labeled free-body vector diagram showing al of the forces acting on the hiker, and the hikers acceleration. Clearly label the force vectors in your diagram so that it is clear which agent is exerting each force. In your diagram, include the magnitudes of any known vectors, with units B. The tension in the vertical portion of the rope is equal to ) 568N i) 618 N i) 588 N. ) 30N. v) 19,600 N vi) none of the above C. Draw a complete and fully labeled free-body vector diagram showing al of the forces actina on the truck, and the truck's acceleration. Clearly label the force vectors in your diagram so that it is clear which agent is exerting each force. In your diegram, include the magnitudes of any known vectors, with units D. The force of static friction which the ground exerts on the truck is equel to 1000 N in the negative x direction. li) 1000 N in the positive x drection. ) 1618 N in the negative x direction. v) 1618 N in the positive x direction. v) 588 N in the negative x direction vi) 588 N in the positive x direction vi) none of the above. C-21
