a 2000 kg truck is used to pull 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 horizontally behind the truck and passes over an "ideal" fricitionless pulley. the hiker hangs on to the other end of the rope. the truck and the hiker both accelerate at a rate of 0.5 m/s^2. assume the rope has negligible weight and that air resistance is negligible.
a) the tension in the vertical portion of the rope is equal to
b)the force of static friction which ground exerts on the truck is equal to
