Question
figure shows a collision between three balls of clay. The velocities and masses of particles are provided in the left figure below. The three balls hit simultaneously and stick together in right figure.
a) The three baslls stick together at the origin during their collision, which is perfectly inelastic. Model the three balls of clay as particle 1( moving north), particle 2 (moving east), and particle 3 (moving south east). On right figure show schematically the direction and magnitude of the resulting momentum of clay blob after the collision? ( your answer will be in terms of variables, not a number.)
b) what is the speed of resulting blob of clay after collision? show below the direction of the resulting velocity of clay blob after the collision. Clearly show your work and explain the reasoning.
c) what is the direction of the resulting blob of clay after the collision?
angether at the origin daring their collision, which is perfeeity inclastic. Model the three westh, and particle 3 (moving southeast) On right Figure of the resuiting momentum of clay blob after collision? (Your answer (a) (S points) The three baills stick show schematically the direction and will be in terms of (b) (5 points) What is the speed of the resulting blob of clay after collision? Show below the direction of the resulti velocity of clay blob after collision Clearly show your work and explain your reasoningExplanation / Answer
(A) applying momentum conservation,
(0.040 x 4)(cos45i - sin45j) + (0.030 x - 3i) + (0.020 x 2j) =pf
pf = 0.023i - 0.073 j kg m/s
magnitude = sqrt(0.023^2 + 0.073^2) = 0.077 kg m/s
direction = tan^-1(0.072 / 0.023) = 72.3 deg below the x axis Or - 72.3 deg
(b) vf = p / (0.020 + 0.030 + 0.040)
vf = 0.852 m/s
direction -> - 72.3 deg
