Oh, we learned that Net force of barge B for example = ΣFbarge B = all the forces acting on barge B so we would do ΣFbarge B = FCrope 2, barge B + FCwater, barge B + FGEarth, barge B + FCbarge B, Earth + FCrope 1, barge B I know it probably sounds weird, it did to me at first as well, but it's...

Contact force is what we are being taught. It is the a force that one object exerts on another object only when the two objects are in physical contact. It is a part of Newton's third law which states whenever two objects interact they exert on each other forces that are equal in magnitude but...

The ball's acceleration the instant before the collision would be equal to gravity (9.8m/s^2) and after the collision since it is moving in the opposite direction a=-9.8m/s^2. The ball's mass doesn't change, again the unknown is time. If I am not mistaken this in an isolated system? If so then...

My apologies, I am very new to this site. I have reposted the question with the provided template. Thank you for letting me know!

Homework Statement A boat pulls two barges down the river. The barge connected to the boat (barge A) has an inertia of 2x10^5 kg, and the other barge (barge B) has an inertia of 3x10^5 kg. the resistive force between barge A and the water is 7x10^3 N, and the resistive fore of barge B to the...

A 1.2kg ball dropped from a height of 3m onto a steel plate rigidly attached to the ground bounces back up to a height of 2.5m.(a). What is the impulse delivered to the ball by the plate? (b). What is the coefficient of restitution of the collision?I know my instructor wants me to use something...

A boat pulls two barges down the river. The barge connected to the boat (barge A) has an inertia of 2x10^5 kg, and the other barge (barge B) has an inertia of 3x10^5 kg. the resistive force between barge A and the water is 7x10^3 N, and the resistive fore of barge B to the water is 9x10^3 N. The...
