1)The motion of a very massive object can be minimally affected by what would seem to be a substantial force. Consider a supertanker, with a mass of 2.3
1) a = F/m = 100000/2.3E8= 4.35E-4 m/s^2
v = v0 + a t
6 = 4.35E-4*t
t = 6/4.35E-4= 13790 s
2)
propulsion force up
air resistance and weight down

Astronomers have observed a small, massive object at the center of our Milky Way galaxy. A ring of material orbits this massive object; the ring has a diameter of about 10 light years and an orbital speed of about 210 km/s . A) Determine the mass of the massive object at the center of the Milky Way galaxy. Give your answer in kilograms. B) Give your answer in solar masses (one solar mass is the mass of the sun). C)...
When a small object approaches a much more massive object, the smaller object can be tidally disrupted. The distance of the closest approach before being tidally disrupted is the Roche limit (recall lecture on rings of plan- ets). If the small object is a star and the large object is a supermassive black hole, the Roche limit is given by where RS is the Schwarzschild radius, ρ̄BH is the average density of the black hole and ρ̄∗ is the average...
(1 point) The motion of a solid object can be analyzed by thinking of the mass as concentrated at a single point, the center of mass. If the object has density p(x, y, z) at the point (x, y, z) and occupies a region W, then the coordinates (x, y, z) of the center of mass are given by 1 1 yp dV zpdv, m Jw AP dx m Jw where m Swpdv is the total mass of the body....
Consider an object in uniform circular motion. A.) If the trajectory and the mass of the object are unchanged, but the centripetal force is doubled, is the object's speed multiplied by a factor of 1, square root of 2, 2, or 4? B.) If the mass of the object is halved and the radius of the circle quadrupled, while keeping the mass of the object the same, is the object's speed multiplied by a factor of1, square root of 2,...
Does a force applied to an object always produce motion? What can you figure out about the forces on an object just by observing its motion? If no forces are acting on a body, can the body be in motion? Explain.
stop getting this sh1it wrong (1 point) The motion of a solid object can be analyzed by thinking of the mass as concentrated at a single point, the center of mass.

What happens to the motion of an object under the influence of a single constant force as you decrease the object’s mass? A) the magnitude of the acceleration would increase B) the magnitude of the velocity would increase but the acceleration would remain the same C) the magnitude of the acceleration would decrease D) the magnitude of the velocity involved would decrease but the acceleration would remain the same
An object in circular motion requires a centripetal force to maintain that path. What force would be responsible for keeping the bugs on the disk? If you look closely at your results, you will see that the acceleration vectors do not point exactly at the center of the circle. Why is this the case?
An object can possess kinetic energy, the energy of motion, and/or potential energy, the energy of position. Energy can be transferred in many ways, one of which is in the form of work. Work, w, is the energy transferred when an object is caused to move a distance, d, against a force, F. Mathematically, we would write this as w=Fd Force is the product of mass, m, and acceleration, a: F=ma When the acceleration is due to gravity, the symbol...
1. A small object is undergoing uniform circular motion. The uniform circular motion is caused by a force that is directed toward the center of the circle. What is the work done by this force during one rotation of circular motion?
