The space shuttle is in a 400km - high circular orbit. It needs to reach a 700 km -high circular orbit to catch the Hubble Space Telescope for repairs. The shuttle's mass is 6.50 x 10^4 kg.
ow much energy is required to boost it to the new orbit?
What is the speed of the second asteroid? Now suppose that the first and second asteroids carry charges of 3.68 C and -3.68 C, respectively. How fast would the second asteroid have to be moving in order to occupy the same circular orbit as before?
A 700 N car traveling at 25m/s.The breaks are applied suddenly and the car slides to a stop. The average breaking force between the tires and the road is 7100 N.How far will the car slide once the breaks are applied.
As a spacecraft approaches a planet, the rocket engines on it are fired (turned on) to slow it down so it will go into orbit around the planet. how long (in minutes) must the engines be fired
A long solenoid of r =1cm and lnght l=1m is inserted into another long solenoid of radius r=3cm, Find the mutual inductance of the two solenoids
The escape speed from the Earth is 1.12 × 10^4 m/s, so a gas molecule traveling away from Earth near the outer boundary of the Earth's atmosphere would, at this speed, be able to escape from Earth's gravitational field.
