3. In a two-stage rocket, the exhaust velocity for the first stageburn is 3000 m/s and for the second stage burn is 3000 m/s. Assumethat during the entire sequence of burns the rocket is still nearenough to the surface of the earth to approximate the externalgravitational acceleration as 9.8m/s^2 , and ignore air resistance.The mass of the first stage engine and tanks is 2000kg. The mass ofthe fuel held in the first stage is 4000kg. The first stage fuelburns in 10 seconds. The first stage is then ejected. The mass ofthe second stage engine, tanks, and payload is 2000kg. The mass ofthe fuel held in the second stage is 2000kg. The second stage fuelburns in 5 seconds. (The second stage tanks remain attached to thepayload when empty.) (a) At what speed is the second stage/payloadcombination moving at the end of the second stage burn? (b) Howmuch faster is this than the speed if all the 6000kg fuel wereburned in the first stage in 15 seconds with the same exhaustvelocity (3000m/s) and the entire 4000kg assembly of the emptyrocket remained in one piece?

4. A particle with mass 10kg starts from rest at r = 10 and ?=0radians, following the trajectory given by r=10-2t , ?=0.2t. Findthe radial and angular components and of the force, as functions oftime, that will cause this motion

5. A sheet of material, mass 2kg, uniform density, is in the shapeof a right triangle bounded by the lines y=0, x=0, and y=4-x. Itattched to the origin, and free to rotate about the y axis. A forceof 1000 Newtons is applied perpendicular to the plane, located atthe x=4 point on the triangle as it starts to rotate. In aright-handed coordinate system, how fast will the object bespinning (in radians per second) as it crosses the y-z plane (thatis, when it has rotated through 270 degrees)?

Thank you in advanced.

The Saturn V, developed at NASA Marshall Space Flight Center (MSFC) under the direction of Wernher Von Braun, was the largest in a family of liquid-propellant rockets that solved the problem of getting to the moon. A total of thirty-two (32) Saturns of all types were launched, not one failed. The three stage Saturn V was taller than a 36 story building and was the largest, most powerful rocket ever launched. Fully loaded with the Apollo spacecraft onboard, it had a mass of 6.8 million pounds. This was still no match; however, for the five powerful rockets that controlled the first stage with 33,560,000 newtons of thrust upwards. Using this information find the net acceleration (m/s2) of the Saturn V rocket. Assume that there is no change in mass,the rocket stays completely perpendicular, and there is no drag on the rocket. This takes place on planet earth with g=9.8 m/s^2.
