A red cart is moving rightward with a momentum of 100 kg•cm/s when it collides with a blue cart that is also moving rightward with a momentum of 80 kg•cm/s.
The collision causes the red cart to slow down and the blue cart to increase its
momentum to 140 kg. cm/s.
Enter the momentum values of each individual cart and of the system of two
carts before and after the collision. Also indicate the change in momentum of the
carts and of the system.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

Ametal ball with a mass of 0.028 kg is dropped from rest at a height of 1.0 meters above the ground. assuming the energy in the ball is conserved, how much kinetic energy will the ball have when it is 0.5 meters above the ground?

Does current flow through or across a resistor?
