Two children fight over a 200 g stuffed bear. The 25 kg boy pulls to the right with a 15 N force and the 20 kg girl pulls to  the 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?
A rope is used to pull a 2.89-kg bucket of water out of a deep well. a. What is the acceleration of the bucket when the tension in the rope is 30.2 N?b. If starting from rest, what speed will the bucket have after experiencing this force for 2.16 seconds?
A train starts from rest and accelerates uniformly, until it has traveled 3.3 km and acquired a velocity of 48 m/s. The train then moves at a constant velocity of 48 m/s for 430 s. The train then decelerates uniformly at 0.065 m/s?, until it stops. a. What is the acceleration during the first 3.3 km of travel? b. How far in kilometers does the train travel during the period of deceleration? c. What is the duration of time required for the train to decelerate?
