Question

During a time interval of one second, a ball moves in the +x or -x direction (that is, to the right or the left), and a net force acts on the ball in the +x or -x direction. For each motion listed below Check all the descriptions of net force that could produce that behavior. More than one description may be valid for a particular motion. a) ball permanently at rest net force = 0 net force to the right with increasing magnitude net force to the right with decreasing magnitude net force to the right with constant magnitude net force to the left with constant magnitude net force to the left with increasing magnitude net force to the left with decreasing magnitude b) ball moving to the right at constant speed Onet force to the left with constant magnitude Onet force = 0 net force to the left with decreasing magnitude net force to the left with increasing magnitude net force to the right with increasing magnitude net force to the right with decreasing magnitude net force to the right with constant magnitude c) ball moving to the left at constant speed Onet force to the right with increasing magnitude net force to the left with increasing magnitude net force to the right with decreasing magnitude net force to the left with constant magnitude net force to the left with decreasing magnitude net force to the right with constant magnitude net force = 0 d) ball moving to the right with increasing speed

Answer 1

126 | 27 28 29 30 31 N force 1.) moving to right with decreasing magnitude there for acceleration is decreasing. Net force to right with decreasing Magnitude (1) Moving to left with increasing Magnitude therefor a celeration is increasing Net force to left with increasing magnitude 170) Net force to left corith deereasing. magnitude

10) Ball is permanently at rest year 28 a 20 " Net no a mano force = o. (b) Moving with constant speed lo acceleration is 2010 in het force fama? o. K.) Moving with constant speed so acceleration. is zero. 1. Net force & Fama e o (d) Moving to right with increasing speed there for acceleration also increasing Net force to right with increasing magnitude
