Question

IZIXM A toy train engine (2.6_kg) is moving 0.26_m/s to the right when it collides with a car in the op (3.3_kg) moving 0.15.m/s posite direction, and they stick together. Find the velocity of the engine-car combination as they move off together. Assume "to the right"'is the positive direction. a. 0.02799.m/s b. 0.03068.m/s d. 0.03509.m/s e. 0.02177_m/s f. 0.02559 m/s c. 0.03807_.m/s ZITB oving in opposite directions have velocities Vii,x 14.m/s and v2ix -8.4.m/s. If their masses are m, 3.3.kg and m2 6.9 kg, respectively, and if their collision is perfectly elastic, then predict the velocity of each ball following the collision. 6.
