Question

mA (kg) me (kg) vA 1 (m/s) ve.1 (m/s) v2 (m/s) Mass added to cart B Mass added to cart A .13 0.35 23 100 g 150 g 150 g Data Analys 2. Using your data from Experiment 2, calculate the total initial momentum p1, the total final momentum p2, the total initial kinetic energy K1, and the total final kinetic energy K2 in all 7 cases, and enter them in the table below. p total mAVA meve mBVB mAVA total p2 (kg m)/s Mass added to cart A Mass added to cart B p1 (kg m)/s K1 (J) K2 (J) 0 50 g 100 g 150 g 100 g 150 g

Explanation / Answer

Initial momentum, P1 = mAVA+mAVB

Final momentum, P2 = (mA+mB)V2

Initial kinetic energy, K1 = 1/2( mAVA2 + mBVB2)

Final kinetic energy, K2 = 1/2( mA+mB)V22
