A 48.0-kg body is moving in the direction of the positive x axis with a speed of 389 m/s when, owing to an internal explosion, it breaks into three pieces. One part, whose mass is 9.5 kg, moves away from the point of explosion with a speed of 385 m/s along the positive y axis. A second fragment, whose mass is 3.0 kg, moves away from the point of explosion with a speed of 413 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity.

M= 48kg

M1 = 9.5kg

M2= 3 kg

M3= 35.5 kg

Fnet = 0

2. Relevant equations

p=mv

m1v1+m2v2+m3v3=mv0

3. The attempt at a solution

been trying to do p = 48*389 = 18672

then 3*-413 +35.5 * Vx = 18672

then get vx of 560.87

then do vy = 9.5*385 + 35.5 vy = -103.02

then vx^2+ vy^2 = v3^2 and i get 551.33 and its not accepting
