Two equal mass carts approach each other with velocities equal in magnitude but opposite in direction. friction can be neglected. if the carts collide completely inelastically, what will be the final velocity of the combined system?

to the left with half the initial velocity
not enough information!
0
to the right with half the intial velocity

0

Explanation:

Since momentum is given by:

Therefore momentum is a vector quantity in the direction of velocity.

This case can be described mathematically as:

since the mass and velocity are equal:

net momentum:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

iron would move it is magnetic there is a mag field around the current in the wire
