2. A rocket of mass m is fired vertically from the Earth, with an initial speed U. It rises to a height R/2 before falling back to Earth, where R is the radius of the Earth. Calculate U in terms of G, M (the Earth's mass) and R. The rocket is fired with the same initial speed, but this time at an angle 45° to the horizontal. Calculate its angular momentum J and total energy E, and use these to...

A test rocket at ground level is fired straight up from rest with a net upward acceleration of 25 m/s2. After 12.0 s, the motor turns off but the rocket continues to coast upward with insignificant air resistance. What maximum elevation does the rocket reach? 6.4 km 3.3 km 8.9 km 4.1 km 5.2 km

A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.2 m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2. (You will need to consider the motion while the engine is operating separate fronm the free-fall motion.) (a) How...

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

An unstable particle is created in the upper atmosphere from a cosmic ray and travels straight down toward the surface of the earth with a speed of 0.99539 c relative to the earth. A scientist at rest on the earth's surface measures that the particle is created at an altitude of 48.0 km. Part A As measured by the scientist, how much time does it take the particle to travel the 48.0 km to the surface of the earth? IVO...

Problem 1,2,3.
MEEN 2302 Sum 2019 HW1 Name Problem 1 12-4. Traveling with an initial speed of 70 km/h, a car accelerates at 6000 km/h2 along a straight road. How long will it take to reach a speed of 120 km/h? Also, through what distance does the car travel during this time? Problem 2 An object freely falling through the atmosphere has an acceleration a -32.2 [1- (v'/160,000)] ft/sec', empirically determined. This equation accounts for drag from earth's atmosphere. If...

A rocket carrying a new 945-kg satellite into orbit misfires and places the satellite in an orbit with an altitude of 175 km, well below its operational altitude in low-Earth orbit. (a) What would be the height of the satellite's orbit if its total energy were 450 MJ greater? km (b) What would be the difference in the system's kinetic energy? (Include the sign of the value in your answer.) Mj (c) What would be the difference in the system's...
