A meteor starts very far from a star (mass 6.49x10^30 kg), so the gravitational attraction is effectively zero. At this distance, the meteor is moving toward the star at 7.03 km/s. Find the speed of the meteor, in km/s when it is distance 9.34x10^12 m from the star.

An experiment is performed in deep space with two uniform spheres, one with mass 20.0 kg and the other with mass 108.0 kg . They have equal radii, r = 0.30 m . The spheres are released from rest with their centers a distance 40.0 m apart. They accelerate toward each other because of their mutual gravitational attraction. You can ignore all gravitational forces other than that between the two spheres. A. When their centers are a distance 28.0 m...

A shooting star is actually the track of a meteor, typically a small chunk of debris from a comet that has entered the earth’s atmosphere. As the drag force slows the meteor down, its kinetic energy is converted to thermal energy, leaving a glowing trail across the sky. A typical meteor has a surprisingly small mass, but what it lacks in size it makes up for in speed. Assume that a meteor has a mass of 1.5 g and is...

Two stars orbit each other, far from other objects. Star 1 has a mass M1 = 5.0 x 10+30 kg. Star 2 has a mass M2 = 3.0 X 10+30 kg. At a certain instant of time, the positions and velocities of the stars are as follows: Star 1 : ~ r1,i = < 2.0, 0.0, 0 > x 10+9 m, ~ v1,i = < 0.0, 4.0, 0 > x 10+6 m/s. Star 2 : ~ r2,i = < -3.3,...

A typical neutron star may have a mass equal to that of the Sun but a radius of only 12 km. (a) What is the gravitational acceleration at the surface of such a star? (b) How fast would an object be moving if it fell from rest through a distance of 1.5 m on such a star? (Assume the star does not rotate.)

The mass of a meteor with a radius of 1 km is about 9 x 10^12 kg. The mass of a meteor also is proportional to the cube of its radius. Suppose a meteor with a radius of 11.6 km is moving at 1.6 x 10^4 m/s when it collides inelastically with the Earth. The Earth has a mass of 5.97 x 10^24kg and assume the Earth is stationary. The kinetic energy lost by the asteroid in this collision will...

The comet that killed the dinosaurs had an estimated mass of 3.0x1017 kg and was traveling at 19 km/s when it hit Earth's surface. Assuming the comet was heading directly towards the earth, estimate its speed (km/s) when it entered Earth's effective gravitational field (a distance of (5.0x108 m away from its center). The radius of the Earth is 6,371 km, and its mass is 5.972x1024 kg.

Ethan, whose mass is 80 kg, stands at one end of a very long, stationary wheeled cart that has a mass of 500 kg. He then starts sprinting toward the other end of the cart. He soon reaches his top speed of 8.0 m/s, measured relative to the cart. What is the cart’s speed when Ethan reaches top speed? Express your answer with the appropriate units.

A negatively-charged particle of mass 0.001 kg and charge -1 nC is launched from a particle accelerator at an initial speed of 1 km/s into empty space. The particle flies in a straight line toward a very big plate that is uniformly charged. The particle starts 0.9 m from the plate, but reaches no closer than 0.1 m. What is the surface charge density of the plate in N/m2?

In the 23rd century, an Earth probe to the planet Altair IV (mass 2.47x1024 kg, radius 3.12x106 m) has a communications failure. To request assistance, a small projectile is shot toward Earth from the surface of the planet, at speed 17.9x103 m/s (which is greater than the escape speed). Ignore friction and all other objects in the universe, and assume the projectile has no fuel. Find the speed of the projectile, in m/s, when it reaches Earth, which is far...
