An unstable particle with a mass equal to 3.34 x 10-27 kilogram is initially at rest. The particle decays into two fragments that fly off with velocities of 0.981c and -0.868c, respectively. Calculate the masses of the fragments. (Hint: Conserve both mass-energy and momentum.)
m0.981c = kg
m-0.868c = kg
During a game of football, the ball is kicked by the punter with a speed of 20m/s at an angle of 40 degrees above the horizontal. A player on the other team, standing 50m away, starts running to catch the ball immediately after it is kicked. ASsu..
