1. When an object is not in motion, what is the sum of the forces acting upon that object? 2. How can forces cause an object to move, change direction, or stop?
3. In a baseball game, a batter is determined to hit a home run. Describe the motion needed from the batter to achieve this goal.

Kk so your answers are: 1 is The sum of all the forces acting on an object is the net force or resultant force. If all the forces cancel out, the resultant force is zero, else, the unbalanced force will cause acceleration of the object. Force is a vector and hence has both a direction and magnitude. 2 is Depending on the magnitude and direction of the force, it can cause an object to move, stop or change direction. For example, in baseball a pitcher throws the ball with a certain speed towards the hitter, who hits it, thus applying a force to it.  and 3 is friction.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
