1) A 1000 kg rocket travels in outer space at 5000 m/s. The rocket then separates into two sections: a 250 kg section that travels at 8000 m/s, and a 750 kg section. All of this takes place in a straight line that you can consider as your x-axis. (Do not assume kinetic energy is constant throughout this process.)

A) What is the total momentum of the system before the separation?

B) What is the total kinetic energy of the system before the separation?

C) What is the final velocity of the more massive 750 kg rocket section?

D) What is change in the system’s kinetic energy in Joules?

A 5 kg block starting with an initial velocity of 7.69 m/s travels a distance of x m along a rough surface that has a coefficient of kinetic friction of μ=0.15. It then travels up a frictionless ramp at an angle of 17.0⁰ to a height of 1.38 m until it stops. How far does it travel along the rough surface - what is the x? (Note there may be more information provided in the problem statement than you need...

1. Engineers are designing a rocket to be used in deep space. If the rocket is fired from rest in deep space, the total mass of the rocket, payload, and unspent fuel must reach a speed of 1.10 ✕ 104 m/s in order to accomplish other maneuvers. Due to the amount of fuel which is still onboard, the rocket, payload, and unspent fuel will have a final mass of 4.10 ✕ 103 kg. If the design of the rocket is...

5a) A 5-kg object travels at a constant velocity of 25 m/s east on a smooth, frictionless surface. An 8-kg object travels at a constant velocity of 55 m/s west on the same surface and then collides directly with the 5 kg-object. The two objects stick together. What is the velocity of the two-object system, just after they collide and stick together? b) After a .20 kg street-hockey puck is hit, it has an initial velocity of 35 m/s and...
