QUESTION 5 An observer on the ground notices that a rocket of mass M is moving with a velocity V at a given instant. In a very small time dt, the rocket burns a small mass of fuel dm and ejects it backwards relative to the rocket at a speed ve. As a consequence, the mass of the rocket decreases and the velocity of the rocket changes by an amount dV. The increase in the forward momentum of the rocket is balanced exactly by the negative momentum carried by the exhaust gases so the observer on the ground does not see the momentum of the rocket-fuel system changing. What is the new momentum of the rocket (minus the ejected hot gases) relative to the observer on the ground? O dm (V- Ve) O (Ve Xdm) O M(Ve- V) O (M- dm)(V+ dV)

An object is made of glass and has the shape of a cube 0.11 m on a side, according to an observer at rest relative to it. However, an observer moving at high speed parallel to one of the object's edges and knowing that the object's mass is 3.6 kg determines its density to be 8700 kg/m3, which is much greater than the density of glass. What is the moving observer's speed (in units of c) relative to the cube?
An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. One of the fragments has a velocity of +0.811c and a mass of 1.57 × 10-27 kg, and the other has a mass of 5.98 × 10-27 kg. What is the velocity of the more massive fragment (as a multiple of c)? (Hint: This problem is similar to Example 6 in Chapter 7.) Unstable particle at rest V2 m2 m1 V1 Recoiling fragments
The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/skm/s . To the crew's great surprise, a Klingon ship is 140 kmkm directly ahead, traveling in the same direction at a mere 30 km/skm/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 6.7 ss . The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant.
Two manned satellites are approaching one another at a relative speed of 0.235 m/s, intending to dock. The first has a mass of 3.95 × 103 kg, and the second a mass of 10.8 × 103 kg. a)Calculate the final velocity, in meters per second, of the two satellites after docking, in the frame of reference in which the first satellite is initially at rest. Take the initial velocity of the second satellite to be in the positive direction. b)What is the change in kinetic energy, in joules, in this inelastic collision? c) Calculate the final velocity of the satellites, in meters per second, in the frame of reference in which the second satellite is initially at rest. Take the initial velocity of the first satellite to be in the negative direction. d)What is the change in kinetic energy, in joules, in this frame of reference.

4. A rocket accelerates by burning its onboard fuel, so that its mass decreases with time.Suppose that the initial mass of the rocket at liftoff (including its fuel) is m, the fuel isconsumed at rate r, and the exhaust gases are ejected with constant velocity ν (relativeto the rocket). A model for the velocity of the rocket at time t is given by the equationv(t) = −ν ln(1 −Rt) −gt,where g is the acceleration due to gravity, R = r/m, and t is not too large.(a) Find an expression for the acceleration, a(t) = v′(t), of the rocket at any time t.(b) Find an expression for the position of the height, h(t), of the rocket at any timet. You can assume that at t = 0, the rocket hasn’t left the ground. Hint: re-member that ν,R,g are all constants and t is the independent variable.Write out your steps carefully!(c) Let g = 9.8 m/s2, R = 0.005 s−1. What does the velocity of the exhaust gases,ν, need to be for the rocket to reach a height of 6000 m one minute after liftoff?You can round to the…
A particle of mass M, which was initially at rest, is hit by a particle of mass m, which is travelling at the speed Vi. The two particles collide and travel in different directions at the same pace Vf. Find the mass ratio M/m in terms of ß = vi/c, assuming a relativistic, elastic collision. Demonstrate that this reduces to Vi 0, the nonrelativistic meaning.

Astrophysics 14 Use Newton's second law, F = dp/dt, and the formula for relativistic momentum, Eq. ( 44), to show that the acceleration vector a = dv/dt produced by a force F acting on a particle of mass m is F (F. v), ymc² Ym where F· v is the vector dot product between the force F and the particle velocity v. Thus the acceleration depends on the particle's velocity and is not in general in the same direction as the force. mv p = /1 – v²/c² = ymv (44) VI -
