78596693 Ghosn n11 ± A Superball Colides Ine!astically with a Table ± A Superball Collides lne!astically with a Table Part A As shown in the figure (Figure 1), a superball with mass m equal to 50 grams is dropped from a height of h, 1.5m Find the y component of the momentum, Poforn g, Express your answer numerically, to two significant figures. of the ball immediately before the collision, t collides with a table, then bounces up to a height of he = 1.0 m The duration of the colision (the time during which the superball is in contact with the table) is Hints 15 ms. In this problem, take the positive y direction to be upward, and use g = 9.8 m/s for the magnitude of the acceleration due to gravity. Negiect air resistance. Indre,--027 kg . m/s Correct Part B collsion, that is Just as t is leaving the table Find the y component of the momentum of the ball immediately after the Express your answer numerically, to two significant figures Hints Figure 1of Pae0.22 kg-m/s t Before During After Vy Answeo Give Up Correct Part C Find the y component of the impulso meaned to the ball dunng the olson. Express your answer numericaly, to two significant figures. Hints 049 kg m/s My Answers Give U

Explanation / Answer

The magnitude you've put is correct but the asked question was K.E after collision - K.E before collision i.e

Kafter - Kbefore = -0.245 Joules ( Negative value)
