Question

Part 1:A 20.0 g ball of clay traveling east at 3.00 m/s collides with a 30.0 g ball of clay traveling north at 4.00 m/s. To find the total momentum of this system before the collision, we must determine the momentum of each piece of clay and then sum the two momenta vectorially. The 20.0 g piece has a momentum 0.06 kgm/s east, and the 30.0 g has a momentum 0.12 kgm/s north. What is the magnitude of the vector sum of these two momenta?

Part 2:When the pieces of clay collide, they stick together. We will assume momentum is conserved in this collision. What speed must the 50.0 g piece of clay have such that the final momentum is equal to the initial momentum?

For additional work, try to determine the direction of motion of the 50.0 g piece of clay.
