A 15.0 kg plate head explodes into three pieces A 6.0 kg chunk flies off at 12.0 m/s 15o N of W and a 5.0 kg chunk sails at 8.0 m/s 35o E of S. What is the velocity of the final piece?

Homework Answers

Answer #1

Mass of plate , initially the plate is at rest.

Masses of 3 chunks are , and

are unit vectors along positive X and positive Y axes respectively.

Conserving the momentum of the plate and the 3 chunks,

Velocity of 3rd chunk is

Its direction is North of East.

A vessel at rest explodes, breaking into three pieces. Two pieces, having equal mass, fly off perpendicular to one another with the same speed of 45m/s. One goes along the negative x-axis and the other along the negative y-axis. The third piece has three times the mass of each other piece. What are the direction and magnitude of its velocity immediately after the explosion? 1)What is the angle with respect to the x-axis? 2)What is the magnitude of its velocity?
