1. A firecracker is heading due north with speed v when it explodes into two pieces of equal mass. If one piece is traveling due west with speed v, what is the speed and direction of the second piece? Hint: Call the mass of the firecracker m. Draw a north-south-east-west diagram and overlay a coordinate system (pick an x- and y-direction). Write the initial momentum of the firecracker as a vector (include unit vector notation). Once the firecracker splits in half, what is the mass of each piece? Write the momentum of the piece traveling due west as a vector. Set up a conservation of momentum equation (initial momentum of single firecracker = final momentum of each piece added together), where the components of momentum of the second piece are unknown. Split your equation into components in each direction and solve.

You drop a steel ball and a clay ball, both of the same mass, from the same distance. The steel ball strikes the ground and rebounds with almost the same speed. The clay ball strikes the ground and sticks. Assume the collisions occur over roughly the same amount of time. Which ball exerted a greater force on the ground? Select the correct answer with the best explanation. A. The two exert the same force. Since they collide with the same initial momentum, they will exert thesame force.B. The clay ball exerts the greater force. Since it starts with some momentum and ends with no momen- tum, it undergoes a greater change in momentum than the steel ball, which rebounds with the same momentum (no change).C. The clay ball exerts the greater force. All of its energy is transferred to the floor, whereas the steelball rebounds with the same kinetic energy, doing no work on the floor.D. The steel ball exerts the greater force. Since it starts with some momentum and it reverses the direction of…
