A fireworks rocket is moving at a speed of 45.0 m/s. The rocket suddenly breaks into 2 pieces of equal mass, which fly off with velocities v1 and v2. v1 creates an angle of 30 degrees above the x-axis and v2 creates an angle of 60 degrees below the x-axis. What is the magnitude of v1 and v2?

Problem: A projectile (mass = 0.20 kg) is fired at and embeds itself in a target (mass = 2.50 kg). The target (with the projectile in it) flies off after being struck. What percentage of the projectiles' incident kinetic energy does the target (with the projectile in it) carry off after being...
