Two pieces of clay are moving directly toward each other. when they collide, they stick together and move as one piece. one piece having mass 300 g is moving to the right at a speed of 1 m/s. the other piece has mass 600 g and is moving to the left at a speed of 0.75 m/s. a) use momentum conservation to determine the velocity of the combined clay piece after they collide. (note: you can treat this as a one-dimensional problem, but since you're computing velocity not speed, you need to include an appropriate sign. assume the positive axis points to the right; therefore use a positive sign to indicate motion to the right, and a negative sign to indicate motion to the left.) -0.167 m/sb) what fraction of the total initial kinetic energy is lost during the collision? in other words what is (kei−kef)/ kei?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
