A 24g ball of clay traveling east at 3.3m/s collides with a 33g ball of clay traveling north at 2.4m/s .

1a)What is the movement direction of the resulting 57g blob of clay?

1b)What is the speed of the resulting 57g blob of clay?

X = M1*V1 = 24*3.3 = 79.2
Y = M2*V2 = 33*2.4 = 79.2

1a. Tan A = Y/X = 79.2/79.2 = 1.00
A = 45o = Direction.

1b. Momentum = X/Cos A = 79.2/Cos45 = 112

(M1+M2)*V = 112[45o]
(33+24)V = 112[45]
V = 1.96 m/s.[45o]
