In a physics lab, a 0.815-kg cart (A) moving east at 20.8 cm/s collides with a 1.16-kg cart (B) that is moving west at 42.6 cm/s. After the collision, Cart A moves west at 39.2 cm/s. Assume the system is isolated. Determine the final velocity of Cart B and the momentum after collision for cart B. Use the notation that east is the positive direction and west is the negative direction.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
