Question
(a) Status Newton's First Law of motion.
(b) A 2-kg object is affecting horizontally with a speed of 4 m/s. How much net force is necessary to keep object moving at this speed and in this way?
(c) An applied force of 50 N is used to speed up an object to the right across a frictional surface. The object encounters 10 N of friction. Illustrate a Free Body diagram to show forces acting upon the object of mass 8 kg and then determine the normal force, net force and the acceleration of the object. (Neglect air resistance.). Take the value of g to be 10 m/s/s.
(d) Assume that you filled a baking dish to the rim with water and walked around an oval track construction an attempt to total a lap in the least amount of time. The water would have a tendency to spill from container during specific locations on the track. In general while will the water be spilled?
