Two object collide Object A has a mass of 2.50kg and an initial velocity of Via=15.2m/si+25.7m/sj

Object B has a mass of 3.43kg and an initial velocity of Vib=4.25m/si+(-9.72m/s)j

After the collision Object A has a velocity of Vaf=2m/si+15m/sj

Is this collision elastic or inelastic? explain

    Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of mA = 18.0 kg and an initial velocity of v0A = 8.00 m/s, due east. Object B, however, has a mass of mB = 30.0 kg and an initial velocity of v0B = 5.00 m/s, due north. Find the magnitude of the final velocity of the two-object system...

    One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 3.4 and 7.7 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...

    Two objects collide head-on (see figure below). The first object is moving with an initial speed of 7.99 m/s to the right and the second object is moving with an initial speed of 10.00 m/s to the left. Assuming the collision is elastic, m1 = 5.12 kg and m2 = 6.15 kg,determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left.) v1f =...
