Question
A 686 N park ranger uses a basket and a rope-pulley system to transport an injured sea turtle up to a plateau, as shown in the
figure. The sea turtle and basket together have a mass of 50.0 kg. The ranger holds firmly onto the rope and walks away from the
cliff, speeding up at a steady rate of 0.300 m/2
2. He thereby causes the basket (and the turtle) to accelerate straight upwards at
the same rate. Assume that the rope has negligible weight and that the pulley is ideal, having no friction in its bearing. Also
assume that as the ranger trudges along, his feet do not slip on the ground.
