A rocket of mass 10^5 kg is launched from the surface of the Earth. This is a sketch of the rocket as it’s still in Earth’s atmo- sphere. The rocket is undergoing an accel- eration of 3 m/s^2 upward. There is a force exerted on the rocket from the thrust of its engines labeled here as FEngine (you can use FE for short). The rocket is still close to the Earth’s surface, so it is subject to Earth’s gravity, and it is also subject to a substan- tial air resistance force. a. Draw a complete free body diagram of the rocket with all forces acting on it, clearly indicating which direction each forces act. b. What is the weight of the rocket, and what is the net force on the rocket? c. If the force the engine is exerting is FE = 1.8×10^6 N, what is the magnitude of the force of air resistance? d. What is the work done by the engine as the rocket rises 150 m?

Before they were decommissioned, the NASA space shuttles required two solid rocket boosters (SRBs) to launch the shuttle from Earth’s surface. Both SRBs produced 1.7 x10^7 N at liftoff. The combined mass of a shuttle and rocket boosters was about 1.5 x 10^6 kg. (5 marks) (a) Calculate the net acceleration of a space shuttle and rockets at the time of liftoff.

After the NEAR spacecraft passed Mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid Eros, the final destination for the mission. After getting close to Eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 103 m) around the asteroid. So much propellant had been used that the final mass of the spacecraft while in circular orbit around Eros was only 550 kg. The spacecraft took 1.04 days to make one complete circular orbit around Eros. Calculate what the mass of Eros must be.

Look for center 0f mass by caIcuIus 0f a soIid uniform hemisphere 0f M as mass and R as radius with its flat side pointed towards the ground.
Let's say we have a M1 and M2. Let's just say. Let's examine this hypothetical situation. The first mass would be 1.50 kg and the second mass would be 2.00 kg. These two masses would then be separated by a length or we should say a distance of this L = 2.50 m. Let's say we want to place a third mass (immaterial mass) in the middle of the two masses, such that there would be no net force. Find this specific place where this would occur, and to make it easy, find the distance from the first mass towards this third mass
