1.)is it possible to move in a curved path in the absence of a force? Defend your answer.
2.)What is the net force on a 1-N apple when you hold it at rest above your head? What is the net force when you release it?
3.)What is the net force acting on a 1-kg ball in free fall?
4.)When you kick a football, what action and reaction forces are involved, which force, if any, is greater?
5.)Does a baseball bat slow down when it hits a ball? Defend your answer.
6.) Two people of equal mass attempt a tug of war with a 12-m rope while standing on frictionless ice. When they pull of the rope, each of them slides toward the other. How do their accelerations compare, and how far does each person slide before they meet?
The Attempt at a Solution
1.) I have no idea, I would think that the item would just follow the path, and if the path was curved it would curve too.
2.) 0, and then -10m/s because thats the rate at which it falls due to gravity.
4.)The foot kicking the ball, and the ball kicking the foot, and the foot kicking the ball would be greater.
5.) I don't know :(
6.)I don't know. :(
I have a test tommorow, and need answers before then, Thanks!!!
