Final Name 1 (10 points) Here is an ice boat. The dynamic coefficient friction of the steel runners is 0.006 It has a mass (with two people) of 250 kg. There is a force from a gentle wind on the sails that applied 100 Newtons of force in the direction of travel. a What is it's acceleration b What is its speed after 20 second? 2 (10 points) You have two forces in the horizontal plane, are acting on a 1 kg block sitting on a frictionless surface of ice. One force of 10 N is acting on the block from an angle for 45 degrees The other force of 5 N is acting in the direction of 150 degrees from the x axis. Find the net force in Polar/degree coordinates 10 Newton 150 deg 5 Newton 45 degrees Overhead view
You have a solid metal disk with a radius of 0.2 meters, that rotates about its center. It has a mass of 10 kg. You apply a force of 3 N tangentially to the rim of the disk a What is its rotational inertia? b What is the torque? e What is the angular acceleration? 4 (10 points) You fire a cannon horizontally off a 50 meter tall wall. The cannon ball lands 1000 m away. What was the initial velocity? 50 m 1000 m
