Cart Definition and 308 Threads

Three Physics 111 AP students, each having a mass of 60kg, climb onto a large flatbed cart that has a mass of 120 kg. Standing at one end and taking turns they run to the opposite end and jump off, one immediately following the other, each with a velocity of 10 m/s with respect to the cart...

A 1000 kg cart is rolling to the right at 1.70m/s . A 70.0 kg man is standing on the right end of the cart.What is the speed of the cart if the man suddenly starts running to the left with a speed of 7.00 m/s relative to the cart? really boggles my mind, should i be using =(m1 +m2)Vf -...

OK this problem is probably really easy, but I totally have no idea how to handle it. Please help! Here goes: A 20kg cart on wheels has been pushed up against a wall with a spring (k= 244N/m) between the cart and the wall. If the spring is compressed a distance of 0.1m and a force of 20N is...

Force Question - Still want another oppinion! A man pulls a cart on a friction fee surface by means of a pulley and rope. He pulls the rope at 600 N. Now replace the man's action with an iron weight of 60 kg so that it is attached to the end of the rope. The cart is again set in motion. Is...

Hello, I've just joined this forum in hopes of finding some help to my physics problems. I usually can find out what to do by myself, but this problem seems to be requiring some advanced concepts...or it maybe is so that I'm just not using my noodle. A car is sliding down an inclined plane...

I've been having troubles figuring out this question, because the cart is not actually attached to either spring nor always touching one. Any help would be appreciated. A cart moves without friction between two springs, back and forth. Both springs have a spring contact of D = 72 N/m. At...

ok I have another problem here. Please help me. Thank you in advance. A 1.50 kg sled scrapes down a grassy incline where the coefficient of friction is 0.678. The sled moves at a constant speed f 4.50 m/s and it takes 12.5 seconds to travel the entire length of the hill to the bottom...
