... Newton’s First Law: Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force. Newton’s Second Law: Force equals mass times acceleration (F = ma). Newton’s Third Law: For every action there is an equal and opposite reaction. ...

... A baseball (m=0.14kg) has an initial velocity of v0=-38m/s as it approaches a bat. We have chosen the direction of approach as the negative direction. The bat applies an average force F that is much larger than the weight of the ball, and the ball departs from the bat with a final velocity of vf=+58 ...

... Now if we only had a way of knowing the maximum speed (i.e., the speed of the mass when it reaches the lowest point of its motion), then we could make further progress. The other problem is that we don't know r, the length of the rope. I'm not sure what to do about this latter problem, but for the f ...

Chapter 4: Newton`s Second Law F = ma First Law
... Free–body diagrams It is necessary to draw a separate free body diagram for each mass. Then add up all the forces acting on each mass separately, and use Newton’s second law in each case. For mass M the only force acting is the tension T in the connecting string. So by Newton’s second law for M beco ...
