Two children fight over a 200 g stuffed bear. The 25 kg boy left with a 17 N force. Ignore all other forces on the bear (such as its weight).
a. At this instant, can you say what the velocity of the bear is? If so, what are the magnitude and direction of the velocity?
b. At this instant, can you say what the acceleration of the bear is? if so what are the magnitude and direction of the acceleration?
