Question

Four objects are situated along the y axis as follows: a 2.00-kg object is at +3.00 m, a 3.00-kg object is at +2.50 m, a 2.50-kg object is at the origin, and a 4.00-kg object is at −0.500 m. Where is the center of mass of these objects?

1. The four objects are positioned along the y-axis as follows: The object with 2.00 kg mass is at +3.00 m, the object with a mass of 3.00-kg is at 2.50 m, while the object with a mass of 2.50-kg is placed at the origin and the object with 4.00-kg mass is located at -0.500 m. Where's the mass center of these objects? 2. Determine the impulse of a 0.50 kg magazine at rest if thrown at 3 m/s. 3. A 450g ball is moving at a velocity of 4.8 m/s, east when it collides with 900g ball at rest. If the collision is perfectly elastic, find the velocity (magnitude and direction) of each ball after the collision.
