Some soldiers are learning about explosives by using small amounts to blow up basketballs in a controlled setting. The basketball (mass 1.5 kg) is initially rolling to your right, with a speed of 7.9 m/s. After the explosion, there are three pieces. One of those pieces is half of the initial mass, and the other two pieces are each a quarter of the initial mass. The larger piece moves backward (to the left), with a speed of 4.0 m/s. One of the smaller pieces keeps moving forward (to the right) with a speed of 4.4 m/s. If we consider motion to the right to be in the positive direction, and to the left to be in the negative direction, what will the speed be of the last piece? (Leave the sign on the speed to indicate the direction.) Your Answer: units Answer

You release a 3-kg firecracker from rest. At t = 0.4 s, the firecracker is moving downward with speed 4 m/s. At this same instant, the firecracker begins to explode into two pieces with masses mtop = 1 kg and mbottom = 2 kg. At the end of the explosion (t = 0.8 s), the top piece is moving upward with speed 4 m/s.Determine the velocity of the bottom piece at t = 0.8 s.(Hints: Make a momentum vector diagram. Don’t forget to include impulse in your diagram!)

During a fireworks display, a 0.290-kg bottle rocket approaches the top of its trajectory and explodes into two pieces as in the figure. The first piece (Piece 1) has mass 0.190 kg and the second piece (Piece 2) has mass 0.100 kg. Immediately after the explosion, the first piece is observed traveling to the left at a speed of 4.10 m/s and the second piece is observed traveling at an angle θ = 36.0° above the horizon at a speed of 15.0 m/s. Determine the components of the bottle rocket's velocity immediately before the explosion. Vxi = m/s Vyi = m/s
