A dog and a sledge are on the frictionless ice of a frozen lake, 16.3 m
apart but connected by a rope of negligible mass. The dog exerts a certain
horizontal force (N) on the rope. If magnitudes of the sledge and the dog
accelerations are 0.3 m/s? and 0.1 m/s?, respectively. How far from the
dog's initial position (m) do they meet?

- As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 61.0 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmons acceleration and (b) the magnitude of the force F during this interval.arrow_forwardProfessional Application During a visit to the International Space Station, an astronaut was positioned motionless in the center of the station, out of reach of any solid object on which he could exert a force.

- Review. A magician pulls a tablecloth from under a 200-g mug located 30.0 cm from the edge of the cloth. The cloth exerts a friction force of 0.100 N on the mug, and the cloth is pulled with a constant acceleration of 3.00 m/s2. How far does the mug move relative to the horizontal tabletop before the cloth is completely out from under it? Note that the cloth must move more than 30 cm relative to the tabletop during the process.arrow_forwardA magician pulls a tablecloth from under a 200-g mug located 30.0 cm from the edge of the cloth.
