PHYS 1100 : Test 2 Review Worksheet
Document Summary
Leader mel triay: a pack of hunting wolves is being tracked via gps. Scientist record the following movements of the pack: The net displacement is known to be 5. 48km in the direction 74. 5 north of east. What was the direction and magnitude of the third displacement: an object is acted upon by two forces: . What must be the magnitude and direction of a third applied force so that the object can move in the same direction with constant speed: three forces act on an object: What are the magnitude and direction of the object"s acceleration. (note: you may assume that these are the only forces acting on the object: a 1200kg car travelling at 50 km/h slams on the brakes, locking its wheels. It experiences a frictional force of 2. 4 kn. What is the magnitude of the car"s acceleration: a winch is used to move a 120kg block upward with an acceleration of .
