Question

A 10 kg object at rest explodes into four pieces. Each of the three pieces has a mass of 2.0 kg, and the pieces travel due south, due east, and due west, respectively, at 3.0 m/s. What is the magnitude of the velocity of the remaining piece? (A) 1.0 m/s (B) 1.5 m/s (C) 3.0 m/s (D) 4.5 m/s

Answer 1

Answer:

1 m/s

Explanation:

The mass of rest of the pieces is 10kg-(3x2kg)=4kg.

Heavy object moves with less speed as they have less acceleration, but they have more momentum. So momentum of a the 2kg piece = 2x3=6kg/ms, and 4kg piece or the remaining piece's velocity=momentum/4. The momentum is needed. Pls mark me as the brainliest.
