Final answer:
The momentum of a 35 kg object moving at 15 m/s is 525 kg·m/s. In an elastic collision problem where momentum is conserved, the final momentum of the second object after collision is calculated as 50 kg·m/s.
Step-by-step explanation:
The momentum of an object is calculated by the product of its mass and its velocity. The object in question has a mass of 35 kg and is moving at a velocity of 15 m/s. To find the momentum, we use the formula p = mv, where p represents momentum, m is the mass, and v is the velocity. So the momentum, p, of the object is 35 kg × 15 m/s, which equals 525 kg·m/s.
Answering the separate problem provided, in an elastic collision, total momentum is conserved. The initial momentum of the first object is 25 kg·m/s, and for the second object, it is 35 kg·m/s. After collision, the first object's momentum changes to 10 kg·m/s. Using conservation of momentum, 25 + 35 = 10 + (final momentum of the second object). So the final momentum of the second object will be 50 kg·m/s (25 + 35 - 10).
