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. The spacecraft's mass is 2,075 kg and the thrust (force) of the rocket engines is 345 N. If its speed must be decreased by 1,259 m/s, how long (in minutes) must the engines be fired? (Ignore the change in the mass as the fuel is burned.)

A 747 jetliner lands and begins to slow to a stop as it moves along the runway. If its mass is 3.50×105 kg, its speed is 68.0 m/s, and the net braking force is 4.30×105N, what is its speed 11.0 s later? How far has it traveled in this time?
Kenny gets sent to a distant planet of radius 6.0 x 10^5m, and he tries to find out how big the planet is by kicking a sphere of 0.4 kg. He kicks it (with respect to the ground) at an angle of 45o, with a speed of 30 m/s. If the sphere lands 6 seconds later, what is the mass of that planet? Remember, the gravitational acceleration for this planet isn't the same as Earth's!

Europa orbits Jupiter at a distance of 6.7 x 108 m from Jupiter's cloudtops (the surface of the planet). If Jupiter's mass is 1.9 x 1027 kg and radius is 6.8 x 107 m, what is the speed of Europa as it orbits in m/s? Round to the nearest hundredth. Don't worry about putting units, just put the number.

The moon has a mass of 7.35 × 10^22 kg and a radius of 1.738 x 10^6 m. At what speed must a rocket be launched from the moon's surface so as not to fall back to the moon.
A 2kg mass is launched upward initially at 12.1 m/s. A drag force of 0.7v opposes the motion (where v is the speed of the mass). How long does it take for the object to stop at top of its flight? (ANS. = 1.0s)
Suppose the mass of a fully loaded module in which astronauts take off from the Moon is 12,100 kg. The thrust of its engines is 33,500 N. (Assume that the gravitational acceleration on the Moon is 1.67 m/s2.) (a) Calculate its magnitude of acceleration in a vertical takeoff from the Moon. m/s2 (b) Could it lift off from Earth? If not, why not? O No, the thrust of the module's engines is less than its weight on Earth. O No, the thrust of the module's engines is equal to its weight on Earth. O Yes, the thrust of the module's engines is greater than its weight on Earth. O Yes, the thrust of the module's engines is equal to its weight on Earth.

A “doomsday” asteroid with a mass of 1.0x1010 kg is hurtling through space. Unless the asteroid’s speed is changed by about 0.20 cm/s it will collide with Earth and cause tremendous damage. Researchers suggest that a small “space tug” sent to the asteroid’s surface could exert a gentle constant force of 2.5 N. For how long must this force act?
