The motion of a very massive object is hardly affected by what would seem to be a substantial force. Consider a supertanker, with a mass of 2.2*10^8 kg.
If it is pushed by a rocket motor (thrust force of a rocket motor is 5.0*10^6 N)and is subject to no other forces, what will be the magnitude of its acceleration?
A gremlin is a tiny mythical creature often blamed for mechanical failures. Suppose for a moment that a shrewd physicist catches one such gremlin and makes it work for her instead of against her.
An object is thrown vertically upward with an initial velocity of 14.7m/s, how long does it take for the object to be 9.8m from its initial position
a 30-cm tall (height) ad 4.0 in diameter plastic tube has a sealed bottom. The mass of the tube if 30.0g. What is the density of the liquid
The distance between the centers of the wheels of a motorcycle is 150 cm. The center of mass of the motorcycle, including the rider, is 85.5 cm above the ground and halfway between the wheels. Assume the mass of each wheel is small compared to the bo..
A small spinning asteroid is in a circular orbit around a star, much like the earth's motion around our sun. The asteroid has a surface area of 9.5 m2. calculate the equilibrium temperature of the asteroid
A nuclear-fueled electric power plant utilizes a so-called "boilingwater reactor". In this type of reactor, nuclear energy causes water under pressure to boil at 285 °C, by which the temperature of the river rises
A neutron in a nuclear reactor makes an elastic, head-on collision with the nucleus of a carbon atom initially at rest. find the kinetic energy of the carbon nucleus after the collision
David is driving a steady 24 when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.70 at the instant while David passes. How far does Tina drive before passing David.
A car is driven 165 km west and then 95 km southwest. What is the displacement of the car from the point of origin (magnitude and direction)?
A parallel-plate capacitor is constructed with circular plates of radius 6.0×10?2m . The plates are separated by 0.26mm, Find the value of the dielectric constant
Aingly-ionized lithium has a nucleus of charge +3e and two electrons. Use the variational principle to estimate the ground-state energy. Now consider a nucleus of charge Ze with two electrons. Use the variational principle to estimate the ground-st..
