A 1200 kg truck is moving to the right at a speed of 30 m/s. It hits another identical truck that was at rest. The two trucks stick together and move to the right at a speed of 15 m/s. Elastic: m1 v1B + m2 v2B = m1 v1A + m2 v2A Inelastic: mv1B + mv2B = (m1 + m2 ) Vf a. Is this an elastic or inelastic collidion b. What is the total momentum before the trucks collided with each other? c. What is the total momentum after the trucks collide with each other? Hint: be sure to add both masses then multiply by the velocity. d. Was momentum conserved and how do you know?

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
