Homework Statement
Three balls of clay have masses m1 = 106 g, m2 = 148 g, m3 = 120 g, and speeds v1 = 1.48 m/s, v2 = 1.19 m/s, v3 = 1.85 m/s. They move in the directions: (1) at 45° from the horizontal, (2) horizontally left, and (3) vertically up. They collide simultaneously and stick together. Calculate the speed and the direction (angle) of the resulting blob of clay.
Homework Equations
p=mv
The Attempt at a Solution
Vx = 106 * 1.48 * cos(45) - 148 * 1.19 = -65.189882 m/s
Vy = 106*1.48sin(45) + 120*1.85 = 332.0309 m/s
V = sqrt(332.0309^2 + [-65.189882]^2) (answer?)
angle = arctan (Vy/Vx)
This isn't right is it,
