Practice: Firework


A fireworks explodes and forms three fragments of equal mass. One fragment travels directly upward at 14 m/s and the second fragment moves at 25m/s at 25o below the horizontal to the right. Determine the velocity of the third fragment immediately after the explosion.

A radioactive atom at rest with a mass of 100×10−27 kg100\times 10^{-27}~kg is decaying to three particles with masses of 25×10−27 kg25\times 10^{-27}~kg , 40×10−27 kg40\times 10^{-27}~kg and 35×10−27 kg35\times 10^{-27}~kg respectively. Assume that all three particles remain in x-y plane. If the first particle is moving in the direction of positive y axis at speed of 20m/s and the second particle moves in the direction of 25 degree clockwise respect to positive x-axis at speed of 15 m/s, what is the angle and speed of the of the third particle?
